The following testimonials are from coworkers and authors I’ve worked with as their copyeditor, proofreader, or develomental editor.

“I have worked with James for ten books now and I have never been disappointed. James’s attention to detail is unrivaled. I trust him to not only complete a thorough line edit, but also provide insights and feedback to improve my story as a whole. He is professional, courteous, and a JOY to work with. I plan to work with James for the foreseeable future and am thankful each time he helps make my stories shine.”
—Lena Hendrix, author of bestselling contemporary romance

“James is the best proofreader I have ever used. His attention to detail amazes me, and his turnaround times are just as impressive. He responds quickly to emails, and working with him has made me feel so much better about my manuscript and much more confident in presenting my book to the world. I will definitely be asking him to proofread my next manuscript and want to keep writing just so I have excuses to work with him again.”
—Renee Linnell, author of The Burn Zone

—Bethany Crandell

I will 1000% use James for all future projects! Thank you for making my debut novella worthy enough to stand among the other current extreme horror authors!”
—Remy Oliver, horror author

“James Gallagher changed my life. For years I had been researching a story that became overwhelming to produce. So much so that I got bogged down and was no longer able to make any progress. After being introduced to James by working alongside each other on a few corporate projects (which he excelled at), I hired him to help me develop my story. In one full-day session James helped me map my content into a cogent and meaningful narrative as well as add some much-needed juice to take the story to the next level.”
—Mark Korsak, creative director, graphic recorder, illustrator

“A big thank you to James Gallagher for meticulously editing Pride and Wrath, redlining all those commas I love. Your exactness and mastery of the most technical grammar is unparalleled.

—Eva Charles, bestselling romance author

“This edit really went above and beyond what I expected, so much appreciated!”
—David Healey, author of the Caje Cole series

—Brooke Whitaker

“I worked with James at Recorded Books for roughly 13 years and his editing skills were only surpassed by his willingness and ability to help those around him write better. His work set high standards for accuracy and clarity. He worked well independently and in groups, often doing more than his fair share of the work. It was a pleasure working with James for so long and I would definitely recommend him for any editing-related project.”
—Michael Tennyson of RB Media
