Marissa Graff

Marissa has been a freelance editor and reader for literary agent Sarah Davies at Greenhouse Literary Agency for five years. She has her MFA in Writing for Children and Young Adults from the Vermont College of Fine Arts. She also holds an M.S. in Elementary Literacy from Walden University and a B.S. in Childhood Education from Boston University.

Marissa strives to work with clients in a way that teaches them the whys and hows of revision. What excites her most is helping writers understand the reasoning behind what’s working and what may need attention so that they're brave enough to delve into revision. She will be a champion of your story and your ability as a writer to make it shine. She offers approaches to revision but is never prescriptive, always respecting the writer’s creative genius and ability to employ changes. She feels if she’s done her job well, a client should probably never need her help again because she’s given them a crash-course MFA via deep editorial support and/or coaching.

Marissa has been an invaluable freelance editor and second reader for me on a number of occasions, and I value her input highly. She has a very sound grounding in writing craft, but what really stands out is her ability to get straight to the heart of a manuscript’s problems and create a clear and comprehensive set of diagnoses, questions and suggestions for the author. Her notes are always very accessible and incisive, but also wonderfully kind and encouraging. She has a real talent for explaining points in an understandable way, while also making you feel that she’s a friend who is totally on your side.  I’ve been an editor, publisher and agent for several decades, but I have great respect and admiration for Marissa’s abilities. Any author who finds themselves in her generous editorial hands, should feel themselves to be very fortunate.
