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 CV, cover letters, 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.
