I love working with Tricia Callahan and always request that she copyedit my manuscripts. Her attention to detail is impeccable. She’s incredibly attentive to consistency of voice and rooting out moments of redundancy. She expertly untangles the messes I make with my timelines. She’s an indispensable part of the creative team. My books would be far less lovable without her contributions.

Patricia Callahan, copy-editor and proofreader extraordinaire—you are the living embodiment of the expression ‘attention to detail.’

—Jack B. Rochester, author of Wild Blue Yonder

I thought I had sent Tricia a clean manuscript for an easy edit. She found myriad mistakes and problems, even typos, despite people having read through it dozens of times. I also appreciated the comprehensive list of characters, places, scenes, and more that she compiled as she went through the edit. She checked absolutely everything to make sure it was correct. I have a new definition of thorough from seeing her work. 

—Harmon Wilkinson, author of the novel Under Shōko’s Bed

I’ve worked with Tricia for multiple projects and am so happy to have found such a solid, interested, thoughtful, careful editor. She always meets her deadlines, and her work is thorough and improves the overall project. I’d work with her on every single book if I could.

—AB Sigler, partner at Empty Set Entertainment

I would like to thank Patricia Callahan for her sharp, sensitive copyediting and suggestions that improved every page.

—Britt Collins, author of Strays: The True Story of a Lost Cat, a Homeless Man, and Their Journey Across America

Tricia Callahan did a flawless and extremely professional job copyediting an 80K word manuscript for me. She created a beautiful style sheet and in our work process was flexible, punctual and kind—a total pleasure to work with! I cannot recommend her highly enough and very much look forward to working with her again.

—Elizabeth Doyle Carey, author of books for middle grade readers

I also wish to tuck in a quick note of thanks to our copy editor, Tricia Callahan, whose attention to detail made the book just plain better.

—Anthony Tjan, author of Good People: The Only Leadership Decision That Really Matters

When I hired a proofreader after already using a copy editor on my first (40,000-word nonfiction) manuscript, I figured he or she might find a handful of typos and grammatical errors. Instead, I got 2,181 suggested insertions, deletions or formatting changes, and 57 explanatory comments—from Tricia. Wow, was I impressed with her thoroughness and knowledge, and the painstaking work that she did! I can’t possibly imagine recommending a professional any higher than I would recommend Tricia for this service.

—Erik Bork, author of The Idea: The Seven Elements of a Viable Story for Screen, Stage, or Fiction

Tricia caught mistakes that even seasoned proofreaders missed! I’m so glad she was available to check my book one last time before it went to the printers. Tricia was able to work with my tight schedule and I feel incredibly fortunate to have found her.

—M. Yap-Stewart, author of Little Moss, Big Tree

I screened editors for a book manuscript, selected Tricia, and was thrilled with the results. She easily earned five-stars across the board. In fact, Tricia went the extra mile, far exceeding what was expected in terms of quantity and quality of edits. As an indie author on a tight budget, I was concerned about cost. She proved to be worth every penny (and then some). Highly recommend her.
