Books by Dr. Kessler
Decades of clinical experience, written for the kitchen and the gym.
Dr. Kessler co-authored a trilogy on bone health and joint pain with writer Colleen Kapklein. The books make the same approach he uses in practice available to anyone with a fork, a pair of sneakers, and an interest in their own health. He also authored the bone density section of a medical textbook used in physician training.
