Internationally bestselling author Tess Gerritsen took an unusual route to a writing career. A graduate of Stanford University, Tess went on to medical school at the University of California, San Francisco, where she was awarded her M.D.

While on maternity leave from her work as a physician, she began to write fiction and in 1987, her first novel, Call After Midnight, was published. It was just the first of 31 suspense novels that she’s written over a 36-year writing career.  She also wrote a screenplay, "Adrift," which aired as a 1993 CBS Movie of the Week starring Kate Jackson.

Tess's first medical thriller, Harvest, was released in hardcover in 1996, and it marked her debut on the New York Times bestseller list. Her novels have hit bestseller lists ever since.  Among her titles are Gravity, The Surgeon, Vanish, The Bone Garden, and The Spy Coast. Her books have been translated into 40 languages, and more than 40 million copies have been sold around the world.

She has won both the Nero Wolfe Award (for Vanish) and the Rita Award (for The Surgeon). Critics around the world have praised her novels as “Pulse-pounding fun” (Philadelphia Inquirer), “Scary and brilliant” (Toronto Globe and Mail), and “Polished, riveting prose” (Chicago Tribune). Publishers Weekly has dubbed her the “medical suspense queen” and Time Magazine named her novel The Surgeon one of the best mystery/thriller novels ever written.

Her series of novels featuring homicide detective Jane Rizzoli and medical examiner Maura Isles inspired the hit TNT television series "Rizzoli & Isles," starring Angie Harmon and Sasha Alexander.  

She is also a filmmaker.  She and her son Josh produced a feature-length documentary, “Magnificent Beast,” about the ancient origins of the pig taboo. It aired on PBS channels around the country. Their previous film, “Island Zero”, was a feature-length horror movie that was released in 2018.

She lives in Maine.
