I’m always grateful for client feedback, as it helps make me a better editor. Here’s what a few of my clients have said about my services.

“I hired John as a professional editor for my medical school and residency applications. His feedback was very helpful and informative. It taught me how to improve my writing skill during the process. He has my highest endorsement.” –Julie F., Physician/Educator

“I have been working with John for many years, starting with his work editing my PhD dissertation and then throughout my career as a academic. His work ethic, quick turnaround, and useful feedback have helped me improve my writing and gain skills. I look forward to continuing working with him in the future as well.” –Deniz Y., Professor/Academician

“John has been an amazing partner as my editor since 2013, and I cannot thank him enough. He has edited a lot of my work, including term papers, SOPs, fellowship applications, my thesis, and manuscripts. Since English is my second language I always need someone to review my writing, especially for checking grammar errors. John is very responsive, professional, reliable, and talented at his job. He always gives the edits back to me on time, and his thoughtful comments are always very helpful. I think his service fees are also reasonable for the quality. I am so glad to have found John as my editor and strongly recommend that you hire him as your editor. =)” –Yookyung L., PhD student

“John has been my editor throughout my PhD program. He has been an amazing editor for me as I prepared research proposals, publications, and last but not least, my PhD dissertation. On top of his work ethic and providing editing services on time, his work always shone by making my writing precise, succinct, and concise. Another aspect I want to point out is that he always gets back to me whenever there are ambiguities to clarify my meaning, and makes sure to tailor the sentences in a way that I meant to deliver them. I want to quote a statement one of my dissertation committee made to me as feedback on my dissertation: “the dissertation is well written and your advisor and you must put a huge effort into it.” As an international student, that was the last feedback that I expected from my committee, and I thank John for his great editorial work. I am definitely recommending John to my colleagues and friends who need an editor for any kind of important English writing project. Kudos to John!” — Yongduk S., Geoscientist/E&P industry

“I hadn’t worked with any other professional editors before, but I don’t hesitate to say that John is top-notch when it comes to editing in the field of social sciences/humanities. He not only provides technical feedback (i.e., on my writing skills) but he understands the subtlety of the contents and contexts of the texts. His suggestions have made my writing much more refined, rich, and beautiful. I’ve been recommending John Acker to those who want to excel in writing, and I will continue to do so.” — Y. C., Assistant Professor
