I have over 30 years' experience as an editor working with individuals and organizations both freelance and in-house, including Houghton Mifflin, Harcourt Brace, Gorsuch Scarisbrick, Candlewick Press, Charlesbridge Publishing, and Little, Brown. I am also an author, essayist, GrubStreet (Boston) instructor, and part-time psychotherapist. My clients have praised me over the years for being warm and approachable as well as exceptionally detail-oriented and perceptive about the big picture.

I’ve helped novice and veteran nonfiction writers improve their work and get published through careful attention to macro issues such as structure, flow, audience, voice, and purpose; as well as micro issues such as grammar, punctuation, and redundancy. I view my role as a collaborator, coach, and cheerleader. My broad-ranging specialties include creative nonfiction, narrative nonfiction, self-help, memoir, career books, and psychology titles. As an award-winning picture-book author, I consult with prospective or active children’s-lit writers who want help with project concepts, manuscript editing, and/or industry information. In addition, I offer personal coaching to help writers understand and work through writer’s block and other inner obstacles to creativity.

My own publishing credentials include a mindfulness-themed picture book, Charlotte and the Quiet Place (Parallax Press, 2015), illustrated by Sara Woolley, which won the Gold INDIEFAB Medal and the Silver IPPY Award, among several honors. In 2017, Between Sessions Resources published my clinical workbook, Breaking Free of Addiction. My essays have appeared in The New York Times, Salon, Cognoscenti, Boston Globe Magazine, Journal News, The Writer's Chronicle, Writer's Digest, The Manifest-Station, Zone 3, and elsewhere. A scholarly paper on adolescent diary writing appeared in Adolescent Psychiatry.

I am very pleased with Deborah's work. My book was accepted by a publisher and does not require any further editing. That speaks volumes of the quality of her work. I also received valuable tips and advice which I put to good use. I couldn't be happier.

I am really satisfied with the notes she gave me. I am a little overwhelmed about how to implement them and will need to take some time to carefully integrate her ideas into my project. That s...
