Mariah Gumpert – Editor

Nonfiction developmental editor and copy editor specializing in Christianity, spirituality, parenting, self-help, and wellness.

Overview

As a seasoned nonfiction editor, I develop, edit, and adapt content according to the needs of project, audience, style, and brand. I offer developmental editing, line/substantive editing, and copy editing, but my superpower is crafting a piece of writing to make it the best version of itself, to draw out exactly what’s intended for just the audience who needs it. I’m passionate about telling good stories and helping readers find guidance and meaning in their lives.

I work in Christianity/spirituality, family/parenting, self-help/wellness, popular culture, social history, and young adult/juvenile audiences.

Contact me for your spiritual devotionals, your tips for successful stepparenting, your gratitude journals, your takes on cultural trends. Let’s tell the world what you’re passionate about.

Whether I’m doing a line edit on a book about parenting twins or adapting content for a high school reference source on 1960s counterculture, I untangle thorny problems in everything from sentence structure to big-picture approach.

And as we collaborate, I'll help you keep your text focused and targeted while preserving your unique vision and voice.

Let’s tell your story.

Mariah is a very thorough, invested, meticulous editor. She is worth every dollar spent, to the point where I originally wasn't prepared for the quote (my first time writing a book so I didn't know what editing costs!) and then by the end I felt like maybe she should have been paid more because I...
