I'm the author, ghostwriter, or co-author of more than 30 books, including Céline Dion's authorized biography, a Marilyn Monroe biography authorized by her estate, several children's picture books, memoirs, business and leadership books, books for writers, and other adult nonfiction books on topics ranging from fertility to bullying. My books have been featured on The Oprah Winfrey Show, The Today Show, Good Morning America, Dr. Phil, Access Hollywood, The View, Entertainment Tonight, Inside Edition, and in People, Time, and many others.

Some of my books are mine alone, but I most often work as a ghostwriter or co-author both for celebrities and "regular people" with great stories to tell. I've written for all five of the "Big Five" US trade book publishers (Simon & Schuster, Penguin Random House, Hachette, Macmillan, and HarperCollins), and my books have won multiple awards. I also write for magazines and newspapers, including The Washington Post and Writer's Digest.

I hope you'll explore this site and learn more about me and my work. Thanks for visiting!

"Never in my life have I wanted a journalist, a writer, to talk to me again. It’s hard for me to open up and trust. This is the first time I called to say, ‘I want to see her. Ask her if she wants to see me again.’ There’s something about you."

- Céline Dion

"I LOVE working with Jenna! She listens attentively, writes clearly and quickly, and is a joy to be with. She gets my highest recommendation."

- Joe Vitale

"I know in my heart that God hand picked you to help write His story and the role that I played in it. You did an amazing job. I could not have done it without you. I treasure the time we spent together. I am so blessed to have worked with you, but even more blessed to have made a friend in you for life."

- Scott Rigsby

What People Say About Jenna

  • "Since her stellar work on The Marilyn Monroe Treasures, Jenna is the type of writer I am always trying to find projects for. She is an editor's joy: she consistently produces fresh, clean, and compelling prose, meets every deadline, and pours herself wholeheartedly into the success of the project. I would recommend Jenna instantly to anyone looking for a strong and flexible writer for any subject."-Meghan Cleary, editor, becker&mayer!
  • "I worked with Jenna on The Pregnancy Project, a memoir she wrote with Gaby Rodriguez. Jenna is incredibly professional and managed to write—and revise!—a fabulous manuscript under a very tight schedule. The quality of her work is superb and she is nice on top of it! Working with Jenna has been a joy all around, and I wouldn't hesitate to recommend her to anyone in need of a professional non-fiction writer."-Zareen Jaffery, editor, Simon & Schuster
