I’m an award-winning, New York Times-bestselling ghostwriter, developmental editor, and collaborator. 

I partner with experts, thought leaders, and regular people to produce nonfiction book proposals that sell to Big Five publishers and manuscripts that make a mark on the hearts and minds of readers (and sail through the edit process).
