Dr. Leonard Calabrese, is a rheumatologist, immunologist, and doctor of osteopathic medicine. He is the head of Cleveland Clinic's Section of Clinical Immunology and manages the Clinical Immunology Clinic. After graduating from the Kansas City University of Medicine and Biosciences, Dr. Calabrese completed his internal medical training at Cleveland Clinic, followed by a fellowship in rheumatic and immunologic disease.

Over the course of his career, Dr. Calabrese has authored more than 300 publications and become an internationally recognized HIV/AIDS and hepatitis C researcher. He is also passionate about utilizing lifestyle factors such as diet, exercise, sleep and stress management to reduce inflammation, control disease, and bolster immunologic function. Based on growing scientific evidence that environment and behavior play a large role in immune function and gene expression, Dr. Calabrese is leading the charge in educating physicians and empowering patients so that they can feel confident in using wellness behaviors to help strengthen their immune function and improve their overall health and happiness.

Dr. Calabrese and I recently sat down to chat about the basics of the immune system and what practices we can implement in our day-to-day lives to reduce inflammation and lower our risk of chronic disease.
