My Heartful Editor experience was a work of HEART!!! I had such a wonderful experience. Gillian and Sabrena are amazing and were extraordinarily helpful during this process. What I thought was going to be a long and painful experience turned out to be quite the opposite. They both exceeded my expectations. They both made me feel comfortable, confident in my work, and were invaluable resources. Their ability to exceed my expectations and make me feel confident— during what could have been a stressful process— is a testament to their professionalism and dedication. Keep up the awesome work!

I am very pleased with the services provided and would happily recommend the Heartful Editor team to any doctoral candidate. The response time for each submission was remarkably fast, and the edits were thorough. I appreciated that edits were made on the document and also listed and explained in the accompanying email. I had absolute confidence in the suggested edits, yet also felt free to reject any suggestions that did not align with what I desired to communicate. Additionally, all communications were positive in nature and I felt encouragement and support from each team member. The services I received were beyond my expectations, and I found the costs to be entirely reasonable. I am grateful to have selected this team to edit my dissertation.

I am incredibly grateful for the thorough, thoughtful, and generous edits that my editing team (Drs. Gillian Foss, Zach Hooten, and Sabrena O’Keefe) offered to me throughout the process. Working with your team was one of the best decisions I made during my dissertation journey. Thank you, thank you, thank you!

Heartful Editors, Drs. Emily Guetzoian and David Schmid, provided invaluable support and guidance throughout the editing process of my dissertation. Without a doubt, their expertise and dedication played a pivotal role in the completion of my research. From the outset, Emily and Schmiddy, demonstrated an exceptional understanding of the intricacies involved in academic writing. Their meticulous attention to detail was evident in the thoroughness with which they reviewed and revised each chapter of my dissertation. Their keen eye for grammar, punctuation, and sentence structure (especially passive voice) significantly enhanced the clarity and coherence of my work. What truly set Heartful Editor’s apart was their unwavering commitment to my project. They embraced my dissertation as if it were their own, investing time and effort to fully make it the best it could be! Their insightful comments and suggestions not only improved the overall flow of my work but also challenged me to think critically and push the boundaries of my research. Without hesitation, I wholeheartedly recommend Heartful Editor to any scholars seeking editing services. Working with them has been an absolute pleasure, and I am confident that they will continue to inspire other students.

Drs. Roberts and Foss were really encouraging. It was so nice to see encouraging comments throughout my chapters. This balanced the edits and feedback with comments that made me feel like they were truly invested in my work, enough to read it and provide their supportive comments. The feedback was also provided in such a kind and clear way. I never felt pressured to accept an edit because my input and decisions were respected. Communication was great and timelines established were reasonable. I am actually a little sad I’m done because my editing team was so great. Thank you for being part of the process that got me to doctorahood!

What truly set this experience apart was how my Heartful Editors (Drs. Staples and Guetzioan) provided encouragement, support, and prompt responses throughout the entire process. Despite the numerous edits and revisions I had incurred, they managed to maintain a positive and uplifting tone that kept my spirits high. Their kind words and acknowledgment of my efforts boosted my confidence and made me feel valued as a writer. It is a rare talent to balance critical feedback with genuine encouragement, and they exemplifed it with finesse.

The editing team, Dr. Roberts and Dr. Foss, understood my intentions from the start. They are so attentive to the details. I appreciated their positive commentary as well as their gentle coaching. Even though we only met through my dissertation and email, I immediately felt connected with them both. This is a very personal and important time for us as doctoral students and having a team to share with and help you in your journey is PRICELESS.

Working with Dr. Foss and Dr. Hooten through Heartfelt Editor was an exceptional experience as a doctoral student. From start to finish, the entire experience was top-notch. Dr. Foss and Dr. Hooten were highly professional and attentive to my needs, making sure to deliver the best possible results. I was particularly impressed with the level of communication and feedback provided throughout the entire process. I am extremely satisfied with the end product and would not hesitate to recommend your services to anyone looking for high-quality editing. Thank you again for providing such an exceptional experience, and I look forward to working with your organization in the future.

Drs. Foss and O’Keefe were incredible! Not only did they finish all editing well in advance of desired deadlines, they were deeply encouraging, helpful, and constructive in their feedback. The edits to my dissertation were comprehensive and in line with our school’s dissertation guide. I cannot recommend this service more highly!

Andrew Murphy, EdD

This has been an incredible experience! From Day 1, I felt so encouraged by my editors. Schmiddy and Emily clearly outlined how they revised my dissertation with each edit. In one of our correspondences, I told them that they–through their detailed explanation–taught me so much more about APA than any other class or professor. They were so timely in their work and celebrated each of my milestones with me. I tell all my colleagues to go with Heartful Editor. It is so worth the investment!

Alyssa Turner, EdD

The Heartful Editor team (Dr. Henry, Dr. Baker, and Dr. O’Keefe) are simply amazing! The team that worked with me was supportive, clear, and professional. Their technical expertise (APA, copy editing, and writing) led to a seamless final dissertation review and acceptance by my committee, my college, and the College of Graduate Studies at my university. Their enthusiastic support and encouragement also made a huge difference in my experience as I pushed toward the finish line. I felt more confident as a scholar, writer, and thinker as I approached my final submission because of their expertise, expectations, and responsiveness. I highly recommend Heartful Editor!

I could not be any more pleased with my experience with Heartfelt Editor. I will shout your praises to anyone who will listen. You will receive referrals from me. I am so happy with my team—Ashley Staples and Emily Guetzoian. I learned a lot from them and they were pleasant, encouraging, timely, professional, on and on I could go. And, I really appreciate allowing me to pay the very worthy fee as I can.

Sabrena and Suzanne were great! The editors took so much pressure and stress off my shoulders to get all the formatting right (especially with a quantitative study). I know I’m a decent writer and had a decent dissertation, but I wanted something more than that. I have a document I am truly proud of, and that is thanks to the editors.

Nikki Kogan, EdD

I don’t know where to begin; Drs. Emily Guetzoian and Suzanne Baker are all amazing and real-life superheroes saving dissertations all over the globe! I am not exaggerating, but working with you all has been the highlight of my dissertation experience so far besides finishing it. Your expertise, attention to detail, and timely feedback are mind-blowing! I could have never done this without your support. I plan to tell every human I know about Heartful Editor and shout it from the rooftop. If you want me to create a fan club, I will! Seriously thank you so much!

When I said, “We did it!,” I truly mean “we” because without Heartful Editor and my team, Dr. Sara Henry, Dr. Gillian Foss, and Dr. Sabrena O’Keefe, my dissertation would not have been complete. The best decision I made was to contact Sara and choose Heartful Editor. I am beyond thankful; I am grateful. Grateful for the relationship that was built and the positive writing experience from the beginning to the end. Grateful that Heartful Editor and my team remain true to their core values through every interaction and every step of the process – always with love, integrity, and academic excellence. I learned, transformed, and grew as a writer with Gillian, Sabrena, and Sara’s guidance, support, and encouragement. I knew I could ask any question and for anything and they would be there and they were – even 5 minutes before submitting the final version of my dissertation, Dr. Gillian Foss was my savior. Thank you: though the words may be little, they are powerful. Thank you for playing a part in my life, my journey of writing, editing, and ultimately, defending my dissertation. Writing is a vulnerable process. To share that writing with others takes trust. I am forever grateful for Dr. Henry and her amazing team!

I had a fantastic experience and am so happy I chose Heartful Editor for my dissertation edits. My editing team — Tina and Sabrena — were very communicative, very efficient, and provided fantastic support with my document. They had sharp eyes, clear expertise, and took care to ensure their edits still maintained my intended meaning and voice. They were gracious and flexible when my plan and timeline shifted and very responsive throughout. Sara was also great to work with and very transparent during the initial consultation – it was a pleasure to support her business! I recommended Heartful Editor to several of my cohort members who have all been very happy with their experience as well.

I am so thankful to Drs. Dora Elias McAllister and Ally Hartzell for their help during my dissertation process. Not only were they excellent in their editing work, but they went above and beyond to provide advice and support during my dissertation journey. Both of them worked with me to make sure I met all of my deadlines. Knowing you have a wonderful team of professionals reading your work, providing feedback, and making sure you are meeting APA standards was a huge relief as a doctoral student. I highly recommend Heartful Editor!

If anyone needs professional editing services, I highly recommend Heartful Editor! It is not a job for them but a passion and it shows in their work. I had the pleasure to work with Dr. DeAris Hoard and Dr. Kristina Perrelli while completing my dissertation. Their expertise in grammar and APA formatting is second to none. Thank you Dr. Sara Henry for your services. An incredible business!

One of the best choices I made during my dissertation journey was contacting Sara and her introduction to my editor Kristen. The relationship between editor and writer is fundamental to the editing and revising process. Kristen stood beside me as I wrote and edited my dissertation, and her support was so critical while I was writing. I knew If I had a question or needed something changed, she was there. To write takes courage, and to have another edit your work is an act of trust. I am so thankful to Sara and Kristen.

Lisa Boskovich, PhD

Look no further than Heartful Editor! Working with Dr. Henry and her wickedly-talented team was one of the best decisions I made in my doctoral journey. As an administrator, writing like an “academic” took some getting used to, as the dissertation itself is a whole different animal. The Heartful Editor team took my writing to the next level. A quick, affordable, and confidence-assuring process, I cannot accurately express my gratitude for their support and encouragement in helping push me across the finish line. I am so thankful for this team of APA wizards; these behind-the-scenes editors made all of the difference!

When I found Heartful Editor, I was just finishing up my prospectus. My entire committee recommended I get writing support. I was in a time crunch when I found Heartful Editor. I was not the easiest as I was on a tight timeline, and then because of school deadlines, we had to move up the timeline even more. Kristen Tarantino was the perfect mix of encouragement and “get it done.” She worked with me through structure, grammar, and syntax, and I have carried her lessons with me even post-graduation as I continue to write and publish. I was also awarded the Distinguished Dissertation Award, which is in part due to her support. I recommend Heartful Editor to EVERYONE who asks me about editing. I am preparing to use what I have learned to publish from my dissertation and as I look to pen a book!

Cassandra Willis, PhD

During the late stages of my dissertation, I had the good fortune of working with Dr. Caleb Keith at Heartful Editor. From the outset, Caleb took the time to forge a meaningful relationship with both me and my work, guiding me through the process in a manner that was welcoming, informative, and endlessly supportive. As an editor, Caleb significantly improved the quality and precision of my writing, while making sure the manuscript as a whole perfectly adhered to APA guidelines for citations, formatting, and more. In the end, what made working with Caleb so special was his easy and friendly manner and his authentic commitment to editing with heart. I can still remember his enthusiasm when I made it to the finish line – I wouldn’t have made it there without him!

I am so thankful to have found Dr. Sabrena O’Keefe with Sara’s help! She was able to work on a strict deadline and was professional the entire time, and we had a connection being alums from the same university, which made it fun! Above all else, Sabrena was accurate. She fixed all my APA mistakes (and there were tons) and the formatting needed to get approval for publishing. I will use her again and again! Thank you for your time, your work ethic, and your pleasant outlook on making this all possible!

What an amazing experience I had with Heartful Editor! I am so grateful for the support and guidance and timely work. Thank you for working with me to meet my deadline and assist how you did. Megan was fantastic, and I couldn’t be more grateful. At the beginning of December, I remember sitting with my husband in Starbucks, crying crocodile tears, because I couldn’t figure out the formatting for my dissertation. Megan handled it all and just blew me away. She also helped me fine-tune my writing and helped maintain my voice, two things I am immensely grateful for. Your company came highly recommended to me, and you can be assured I will be recommending you to others. Thank you for the good work you do!

Dr. Sara Henry was instrumental in helping me to complete my dissertation. Dr. Henry provided constructive, meticulous, and supportive feedback, which helped to enhance my dissertation. Dr. Henry also asked thoughtful questions throughout the process that assisted in improving the clarity and conciseness of my dissertation. I would recommend to anyone who is completing a thesis or dissertation to work with Dr. Henry and her staff at Heartful Editor. They are dedicated professionals who are invested in helping students become better scholar-practitioners through writing.  I am forever grateful for Dr. Henry and her support.

Working with the team at Heartful Editor was one of the best choices I made during the dissertation journey! Dr. Sara Kathleen Henry was extremely responsive, reliable, and reasonable. Dr. Kim Burdett was the primary editor I worked with and I truly cannot encapsulate how grateful I am for her work. She was timely, thorough, and accessible. I am so proud of the final dissertation I submitted, and working with Heartful Editor certainly helped make that possible.

Constanza A. Cabello, EdD

I finished my Doctorate of Business Administration, and I could not have done it without Sara and Heartful Editor. Sara was thorough on APA and grammar, but even had an understanding of the topic to question how the concepts were explained properly. She truly made my dissertation as perfect as possible. On top of being efficient and delivering a high standard of quality, Sara was easy to work with and really cared about my dissertation process. Thank you, Heartful Editor!

Dr. Sara Henry was an absolute blessing during the dissertation process. I began working with Dr. Henry at the very beginning of the proposal stage and throughout the entire dissertation process. She was professional, detail-oriented, and extremely thoughtful in her editing. She also gave great coaching recommendations to assist me in having a solid final dissertation. I would highly recommend Dr. Henry and the team at Heartful Editor for all your dissertation needs.

Sara has worked with our graduate and doctoral students on theses and dissertations and has edited manuscripts and conference presentations for faculty. She has an incredibly sharp eye for detail in editing and formatting, and her APA expertise is impressive. She provides caring support and guidance to all of her clients and helps us all become more knowledgable about grammar, punctuation, and other common writing issues. We continue to refer students to Sara for coaching and editing, and we enthusiastically hire her for faculty projects!

The timing and introduction to Heartful Editor, and specifically to Dr. Sara Kathleen Henry, was monumental for me within the dissertation process. Her expertise in APA, attention to detail, and genuine commitment to work with me made our entire interaction a smooth one. I know that the finished product was better because of the dedication that she provided to me and my ultimate submission. Her responsiveness was otherworldly, and I am lucky to have had her assistance on this journey.

Michael Cioce, EdD

Since I was conducting research that is considered unconventional, both in the field of education, and in my own graduate program, I knew I needed the right fit. As I was stepping out from the depths of my writing cave, I was fortunate enough to come across Heartful Editor. Dr. Sara Henry exceeded my expectations. I came to her during a critical moment with only weeks left until I needed to complete my dissertation. She addressed the weaknesses in my writing with compassion and clarity, and provided speedy and thorough service. Dr. Henry’s support was invaluable, and for this, I am grateful.

Kahlil Almustafa, EdD

Heartful Editor did a phenomenal job helping my work reach its fullest potential. The folks with whom I had direct contact, Dr. Megan Krone and Dr. Sara Kathleen Henry, provided feedback that not only made important adjustments to my writing, but also was developmental—they helped me to understand how to write with greater clarity and impact in the future. The team at Heartful Editor are doing really fantastic work and are supporting an emerging generation of scholars in wonderful ways. For this I am truly grateful!

Conor McLaughlin, PhD
PhD in Leadership Studies Program
University of San Diego

I had the good fortune of having Heartful Editor recommended to me at the proposal stage of my dissertation, so I was able to work with Sara from proposal to my final product. I had an aggressive timeline for completing my dissertation, and Sara worked closely with me to ensure that we had a plan to get all formatting and editing completed on time. In addition to the editing and formatting, Sara made useful suggestions based on my topic and provided me support in creating charts and other visual representations for my research. Her input improved my final product! Sara was communicative, thorough, thoughtful, and on time throughout the entire process.

Victoria Farris, EdD
Executive Doctorate in Higher Education Management Program
University of Pennsylvania

I only have positive things to say. Sara clearly knows her stuff, which was evidenced by our discussion of the number of spaces after a period. For some, this would be an inane topic, but it demonstrated her knowledge of mechanics, and I especially appreciated the personal touch she brought to a process that could be very impersonal and mechanistic. Her support and encouragement of students at this point in the process is quite helpful. Having Sara do the editing helped reduce the stress, and her approach did so even more!

Gavin Henning, PhD

Sara and Kim did a phenomenal job helping me edit and format my dissertation. A friend of mine introduced Heartful Editor to me only a month before my deadline. I wish I had known about them earlier in my dissertation process. Sara and her team are not only expert editors, but they also have lived experience of being doctoral students themselves. That makes their service so effective, precise, and heartful! I am grateful for their dedication and attention to details. I highly recommend them to other PhD students or anyone who needs editing support.

Azadeh Davari, PhD

University of San Diego

I am glad that I reached out to Sara when it was time to defend and file my dissertation. Sara took the time to speak with me about my research, inquire about how detailed I wanted her to edit my writing, and she was very encouraging to me at a time when anxiety and stress was high. She was very attentive to the minute details of APA formatting. What I appreciated most about Sara’s editorial style is how communicative she was throughout the process and how firmly she held to timelines. I strongly recommend Sara for anyone in need of an editor. She is genuine, personable, thorough, and efficient.

Faraah Mullings Brown, EdD
Doctorate in Educational Leadership Program
University of California, Los Angeles

My faculty advised me to seek out both an editor and formatter to review my dissertation since I was “too close” to my work. When I handed my dissertation over to Sara, I told her that my focus was on content, not formatting. What she returned to me a short time later was a masterpiece ready to submit. The three-article dissertation was new for my university and Sara followed through on her promise to address concerns as they arose. As a result, it was approved well before graduation and I am done! Thanks to Sara, I can now focus on submitting those articles for publication in my field.

Kara Bauer, EdD
EdD in Community College Leadership Program
San Diego State University

I recently needed an editor to work with me on the finishing touches of my doctoral thesis. As you may know, completing a dissertation is a very overwhelming and, at times, frustrating experience. The moment I spoke with Sara, I knew she would guide me through the final stages of the process. My mind was at ease. She has the team approach and I felt as if I was not alone. Sara’s work is exceptional. She is an expert as an editor. She was able to complete the editing process on my timeline, which was not long. This is important when final edits are needed in order to graduate! I highly recommend the services of Heartful Editor. I will be calling on Sara shortly for help with my resume and any other editing needs.

Patricia Corbett, EdD

I was facing a tight deadline and had no time for editing. I needed to focus on complicated family nurse practitioner content, and the technical aspects of the paper included pharmacology, pathophysiology, physical assessment, nursing research, and much more. I was anxious about editing intense medical jargon, but Sara is enthusiastic about her clients’ success and rose to the challenge with superb editing and formatting.

Susanne Cohen, RN

I wish I’d had the opportunity to access Heartful Editor’s services earlier in my dissertation process, as the editing comments and suggestions where extremely valuable. My editor, Dr. Megan Krone, was flexible and attentive, and her experience with and knowledge of the process, her ability to work within the timeline and respond in a timely manner to my communication, and her attention to detail really made the experience pleasant, and this made me believe I could trust Heartful Editor to complete the work!

Eric Brown, PhD
PhD in Leadership Studies Program
University of San Diego

Heartful Editor took such interest and care in my project, delivered on timelines and on quality, communicated often and thoughtfully, and understood both the process and the content. The clear and consistent communication was wonderful. I also really appreciated the process of using track changes and making decisions about how to communicate with each other about what was changing along the way. I was very satisfied with the experience and highly recommend Heartful Editor!

Kimberly Sluis, EdD

Heartful Editor provided committed customer care and quality editing. Jennifer and I were able to establish a trusting relationship—the relationship with both Sara and Jennifer was positive because of the caring and effective communication, the follow through, and their commitment to meeting the goals and vision of the project. They cheered me on with a thorough review of every word. I have a deep sense that whatever happens in my life going forward, I have found a trusted editor in Sara and Heartful Editor. I had an incredible experience!

Anne Buchanan

I cannot speak more highly of the service Sara provided and the great quality of the work she provided. She made the process incredibly easy and was very open to working with me and the needs I had as I finalized my dissertation. The quality is what I appreciated most. In looking over the work, I know that it was taken care of by a very knowledgeable and professional individual. I am very grateful for the help that Sara and Heartful Editor provided!

Efren Ponce, EdD

I will always trust Heartful Editor! The best part was the personal coaching. I never felt like I was a bother, even when I wanted additional clarification. Because of that, I learned a lot throughout the process, and I especially appreciated Sara doing additional research to make sure her feedback was individualized to my unique dissertation.

They truly do coach and edit with love. Sara made the end of my dissertation process as smooth and painless as possible, all the while helping me learn how to avoid and fix common errors so that my future writing will be better. She was in constant communication with me, and I never worried about missing a deadline with her help. I will be referring anyone with editing needs to Heartful Editor. Sara and her team truly saved the day!

I am so pleased that I chose to work with Sara and Heartful Editor at the end of my doctoral journey. Early on, it became evident that I was working with someone who was so much more than just an editor. Sara cared deeply about my work, and on more than one occasion, she was my loudest cheerleader at the end of a long academic journey. I learned a great deal about academic writing during my time working with Sara, and am grateful for her talent, professionalism, and support.

Jason Campbell-Foster, EdD

Sara and Karen are very knowledgeable and thorough. They both worked so hard to meet deadlines, turn drafts around quickly, and work with me on any and everything I was required to do for my university. The thing I appreciated the most was the sincere love and support they showed me throughout the entire process, and the ease of communication.
