I do a little Story Grid style developmental editing over here: https://www.storyscopemd.com/.
Short stories only.
Joanna Penn describes developmental editing this way: “It’s when an editor basically acts more like a creative partner…”
I endeavor to go beyond that by dealing with writers holistically as people who need purpose, balance, and perspective in order to stay motivated and satisfied with a writing career.
I work exclusively with open-minded short story writers who love reading tons of nonfiction.
