“Finest young editor under the sun, moon, and stars.”

—Richard Nash, digital media consultant, entrepreneur, former publisher of Soft Skull Press

“Anne Horowitz is the kind of copyeditor a writer can only dream of.”

—Dani Shapiro, author of Signal Fires

“When I was editing an anthology of essays about working through mental illness, I asked Anne Horowitz to work with some of the writers, many of whom were inexperienced, to strengthen their stories and polish their prose. She did a marvelous job, so much so that I asked her to critique a collection of personal essays I was writing. Her feedback, related to both style and substance, was invaluable, and I will definitely work with her again. I am an Anne Horowitz fan.”

—Lee Gutkind, founder and editor, Creative Nonfiction

“I was delighted—more than delighted, actually stunned—by how intimately you engaged the text, how meticulous and how sensitive your responses to it were. Every writer wants—even more than they fear—to be read that closely, and that intelligently. Thank you so much. It wouldn’t be the book it (now) is without you.”

—Matthew Specktor, author of American Dream Machine

“Anne Horowitz is a class act both as a person and as an editor. I trust that she will have my back for a long time to come.”

—Mark W. Moffett, author of The Human Swarm: How Our Societies Arise, Thrive, & Fall

“I've always had respect for copyeditors, but the copyediting process for my third novel has left me inebriated with gratitude for what these specialized editors do—or rather keep us from doing—on the published page. I look back on my connection with Anne not as a relationship of circumstance, as copyeditor to author, but rather as a deeply personal alliance built on the principles of clear communication. She was more than a copyeditor; she was an online therapist of sorts—the newfangled kind you can text at a dark hour when your writing needs a friend.”

—Courtney Maum, author of Costalegre, in “Ode to a Copy Editor,” article in Poets & Writers (July/August 2019)

“I just wanted to say thank you for your close read of Stilwater. I loved your suggestions, valued your insight and just felt grateful for each red mark on the page. You did a magnificent job with the manuscript at a time when I have almost become blind to the words. Thank you for your contributions to this emerging piece of collective art . . . With respect and gratitude.”

—Rafael de Grenade, author of Stilwater: Finding Wild Mercy in the Outback

“Working with Anne Horowitz on Confessions of a Teenage Jesus Jerk was an absolute pleasure. She dug into the narrative and knew how to work with the strengths of the story to make them pop even larger. Her guidance and understanding of how to work with writers is excellent. She took the work to a new level.”

—Tony DuShane, author of Confessions of a Teenage Jesus Jerk

“I LOVE Anne Horowitz and feel lucky to have such an insightful editor. She is a developmental editor extraordinaire who understood what I wanted to express and helped me write it more clearly and convincingly. I’m grateful for such supportive and critical guidance. I highly recommend her.”

—Elizabeth Enslin, author of While the Gods Were Sleeping: A Journey Through Love and Rebellion in Nepal

“Anne is an exceptional editor. Her notes are meticulous and clearly conveyed, her criticisms constructive and right on the money. I am constantly amazed at the depth and precision of her insights. She is a treasure, the most talented and gifted reader whose suggestions make everything I write so much better.”

—Janice Shapiro, author of Bummer and Other Stories

“Anne is amazingly insightful and thorough with her comments. Her spot-on critiques are done with a generous spirit. Instead of feeling overwhelmed, I was excited about revising my memoir. I knew it would be a much better book after working with Anne.”

—Louise Nayer, author of Burned: A Memoir and teacher at the San Francisco Writer’s Grotto

“Just want to thank you so much for the incredible editorial work. I’m blown away by your talent and effort, and though I am new to this, I can’t help but think you went above and beyond. I really believe the book wouldn’t be where it is without your guidance, and I’m convinced that you’ve helped me exceed my abilities.”

—Chris Cole, author of Body of Chris: A Memoir of Obsession, Addiction, and Madness

“I can’t tell you how much I like working with you. You are quite amazing at this task. I’m so glad I get to see the manuscript through your eyes. I wanted you to know I’m happy to have you. Back to work now!”

—Joshua Braff, author of The Unthinkable Thoughts of Jacob Green, Peep Show, and The Daddy Diaries
