I specialize in copyediting and proofreading fiction for readers of all ages.

In the past decade I have been hired as the copy editor or proofreader on more than 600 books for clients that include Penguin Random House, Simon & Schuster, Macmillan, and HarperCollins Publishers. In December 2023 I rejoined the Random House Children’s Books team as a senior copy editor.

Among the books I’ve copyedited and proofread are a Pulitzer Prize finalist, two National Book Award finalists, a Hugo Award winner, four Top 10 Books of the Year selections, and several instant #1 New York Times bestsellers.

As of May 2023, I am closed to new clients.

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.

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.
