What Clients Say

Meticulous Editor

Jennifer is a meticulous editor who does not read with blinders on. She has a good sense of the overall project, its audience, and the importance of maintaining the voice of the author. I was very impressed with her skill, her speed, and her thoroughness as she read through a book project twice—first as a copyeditor, second as a proofreader. Would definitely use her again and recommend her highly to others.
