As our national conversation on health continues, The Dr. Oz Show maintains close ties with thought leaders in the medical and scientific community. After four seasons, many doctors and scientists have emerged to have relationships with the show that are helpful by providing advice, appearing as guests, keeping us abreast of the latest scientific research, and acting as communication liaisons or sentinels to medical professional associations, government agencies and more. The medical experts and professionals below have chosen to formalize their relationship with our show at our request. They represent an all-star roster of luminaries who will help us make the best information available to our audience.
