About Dr. Tess Fab

Dr. Tess went to UC Berkeley for college, Brown University for medical school, UCLA for residency, and fellowship at the Andrew Weil Center for Integrative Medicine at the University of Arizona. After 12 years working in emergency and urgent care departments, she felt a calling to better understand the root causes of her patients' chronic symptoms. In between shifts on the COVID pandemic frontlines, Dr. Tess pursued a two-year fellowship at the Andrew Weil Center for Integrative Medicine at the University of Arizona. She used this new knowledge to help friends and family understand their chronic conditions when other doctors couldn’t.
​
Now, Dr. Tess is eager to share her expertise with those struggling to understand their symptoms, whether or not other doctors have been able to find answers or offer effective treatments.
​
Dr. Tess lives in San Diego with her husband, colorectal surgeon Daniel Klaristenfeld, their three daughters, dog, 2 cats, and four chickens. In her free time, she enjoys health research, cooking nutritious meals, doing Pilates, and walking her dog on the beach.
