Can’t rave enough. Jonathan served as the “technical reviewer” for my book, “The Complete Idiot’s Guide to Literary Theory and Criticism,” but what he really did was read the manuscript as carefully and sensitively as any writer could hope for, then offered specific suggestions that made the finished product really sing.

Jonathan was fantastic to work with: professional, dependable, on-time, interesting, funny, and genuinely interested in the work and getting things right. From matters of content (big and small) to important elements of style, Jonathan’s approach to editing is absolutely invaluable. Alpha Books/Penguin USA was smart to hire him for this job, and I highly recommend him to publishers and individual writers alike.

Jonathan provided both copy-editing and editorial services on a book manuscript. His copy-editing was meticulous; his questions about content were insightful; his suggestions about passages that needed re-working were spot-on. As an editor he provided steady guidance. Jonathan’s interventions made the book stronger. He is a pleasure to work with: courteous, prompt, honest. I thought hard about which three attributes from the list to check, since they all apply to Jonathan and his work: fast-turn around, crystal clear results, well-researched and well-informed questions, and fair pricing top the list. I will definitely hire Jonathan again

It was an absolute pleasure to work with Jonathan during the writing and editing of my book, Ready to Go: History and Contributions of U.S. Public Health Advisors. Jonathan quickly grasped and appreciated the spirit and approach of the work, and he was a literary master with an “eagle eye” when it came to saying it carefully and well. His work editing Paul Farmer’s writings soon followed, and it is clear that he is making quite a mark in the the public health literature.

Jonathan is a remarkable editor. He has a smart sense of language and on numerous occasions he has helped me clarify my use of it. He also has a vast fund of knowledge. I would recommend Jonathan without hesitation. He is a pleasure to work with and he consistently follows through, with clever insight and a careful eye.

When Jonathan edits a newsletter or article, it goes from good to great. He always finds more concise and effective ways to say what we need said. We plan to continue to use Jonathan’s editing skills to improve our written communications.

I used Jonathan’s services for both copy-editing and editorial services on a fiction novel manuscript. Jonathan is a joy to work with. He is extremely professional and prompt; friendly and kind; spot-on in his critiques; completely careful and thorough in his copyediting. Nothing gets past him! My book is 1000% better by virtue of Jonathan’s insights. I highly recommend his services to anyone who wants to see a remarkable improvement in writing.

Jonathan Cohen played an instrumental role in polishing my book, ‘Secrets of a Tee Time Girl: Golfers, Scandals and the Beverage Cart’. After it had already been proofread once by a professional, Jonathan not only found 40 more glaring errors in spelling and punctuation, but he also researched my historical references and made several fact-checking corrections. He was always there to speak directly with me and I felt great knowing that I had his meticulously careful eyes reading every word on every page. I am grateful that he was involved in my first book and he is most certainly the person I will seek out when my second book gets closer to completion.
