Marissa is a Hollywood-based fiction editor and the writer’s secret weapon (shh!!). She specializes in science fiction & fantasy but works with authors of all genres to help them develop their craft and write engaging prose. Her editing credits include award-winning indie novels, National Geographic hardcovers, and Amazon #1 bestsellers. She’s also a regular guest on the SFF Audio Podcast where she reviews Philip K Dick stories and other speculative fiction with Paul Weimar and host Jesse Willis. She thinks stories can change the world.


Marissa is a consummate and talented editor, always challenging me to look at my own work with fresh eyes and think again how to make it better. I attribute much of my growth as a writer in the last two years to working with her, and I count it a privilege to have had that opportunity. I cannot recommend her enough.

IN THE COMPANY OF THE DEAD (Pinnacle Award Winner for Best Fantasy)

Marissa is a fantastic editor. … Her line edits are some of the best I’ve seen. I highly recommend her.

THE SCORPION GAME (Quarter Finalist for the Amazon Breakthrough Novel Award)

Marissa has reset my bar for creative collaborators. From the firm guiding hand, to the side conversations about literature, to the different points of view she was able to get me to look at my own work, our time together was invaluable.

THE CASQUETTE GIRLS (Amazon Kindle #1 Bestseller, Publishers Weekly Starred)

It’s kind of creepy, how you get in my head and know what I mean even when I write it badly. Some authors I know resent the edit process, but it felt empowering to share the vision with you. I learned more during these edit sessions about my own weaknesses and how a reader views my words than I have in any other experience.

Your work is extraordinary. I can’t even begin to enumerate what I like about it. It’s all wonderful.

Bayard West


Working with Marissa as a developmental editor was a wonderful experience from start to finish. She identified story issues that had escaped both me and my critique partners and made her suggestions with such insight and enthusiasm that I was left energized rather than anxious about the revisions ahead. I have no doubt my book is much stronger thanks to her guidance. Can’t wait to work with her again!

Editing for the Voices of Reason!

Are you an atheist, humanist or science-loving writer who's looking a professional editor? I'm seeking new clients who write about free-thought, skepticism, and science, or whose love for these things seeps through into their fiction worlds and characters.   Years ago...
