Hi there! I'm an editor with over seven years industry experience. I specialize in adult narrative nonfiction across a broad array of genres including history, politics, memoir and journalism as well as adult commercial fiction, particularly with a romance and women's fiction bent. I view editing as an exercise in empathy, and love working closely with authors to shape the best possible version of their book, to make sure the story they want to tell, the message they want to deliver, and the empowering perspective they want to share, come through clearly.

I am available to provide structural editorial notes to help at the development stage, a closer line-edit for projects that are further along, and specialize in long form editorial letters that assess your project's strengths and weaknesses and help you plan for the best path forward. I am a thorough and thoughtful editor, eager to bring my expertise to your work!

Wow is all I can say about that. Cassidy Sachs was wonderful, and I can only imagine the depth of her talents. Thank you, Cassidy for that trip around your world. All the Best, Mark Loughlin
