Joshua Weitz, M.D. is the chief executive officer and clinical director at Dermatology Associates of Rochester. Dr. Weitz specializes in immunology and is passionate about nonsurgical procedures such as CoolSculpting® and miraDry® that use the body’s natural immune response to produce results that benefit the patient. He’s board-certified in internal medicine, allergy/immunology, and anti-aging and regenerative medicine.

Born and raised in northern Michigan, Dr. Weitz graduated with Latin honors from Colby College in Maine. He earned his medical degree from SUNY Buffalo School of Medicine and Biomedical Sciences followed by an internal medicine residency at the University of Buffalo. He returned to Rochester where he completed a prestigious dual fellowship in allergy/immunology and rheumatology at the University of Rochester.

Dr. Weitz also completed a naturopathic, functional, and regenerative medicine fellowship through the American Academy of Anti-Aging Medicine and Metabolic Medicine Institute. He has published in peer review journals and presented to groups of physicians as well as the public, both locally and nationally. He enjoys clinical research and the goal of advancing our understanding of health and wellness.

Dr. Weitz worked closely with Dr. Robert Loss, Jr., and helped establish an electronic database for Skin Search, the clinical research partner of Dermatology Associates of Rochester.

When he’s away from work, Dr. Weitz enjoys spending time with his family, reading, as well as exploring nature through hiking, skiing, and rock climbing.
