Ghostwriting & Book Collaborator

Get your book out of your head and into the hands of readers where it can start making a difference—for them and for you.

I can help.

I’m a New York Times-bestselling ghostwriter and have been helping others write their books for three decades.

I partner with experts, thought leaders, and regular people with an important message to share to produce book proposals that sell and manuscripts that capture the hearts and minds of readers (and sail through the edit process).

“I have been most fortunate to have the opportunity to work with Kate, as she is beyond talented at converting complex medical topics into easy-to-understand text.

—Dr. Joseph Mercola, founder,, and author of Effortless Healing and Fat for Fuel

Kate is my secret weapon when it comes to content marketing. No matter the client or the project, I know that Kate will deliver the goods—and that they’ll be on time and consistently among the best pieces we publish.”

—Margit Detweiler, founder, Gyrate Media

“People often talk about how important it is to have a good editor or how lucky they are to work with someone who can help them craft their message. But as an editor, I’ve been blessed to have the opposite experience: I feel incredibly lucky to have worked with author and writer Kate Hanley. She is the perfect blend of concrete, prescriptive advice with a Zen-like, reassuring voice. There is real substance behind her work, yet she knows how to make it fun, appropriate and appealing. Her optimism is infectious and working with her is a real gift. She has a unique voice, is completely genuine, and you walk away from an encounter with Kate with a better understand of what’s important in life and your own self-worth. If only we could all have a dose of Kate every day. I highly recommend working with her!”

—Lara Asher, New York Times-bestselling and National Book Award-winning editor, Asher Editorial

Kate helped me deliver a message that has been burning on my heart for quite some time. Because of her professionalism, I am now able to reach women all over and help them in ways I never thought possible. Kate helped me stick to a structure so I could chip away at what would have otherwise seemed overwhelming. She kept right on budget and for that I am thankful. So thankful that I happily moved right into my next book project with her.”

—Kris Reece, author of Build a Beautiful Life Out of Broken Pieces
