He routinely takes patients at the Cleveland Clinic Wellness who are in the midst of struggling with tobacco, heart, diabetic or arthritic problems and coaches them with simple (but persistent) lifestyle changes to be able to live, feel, look and be years younger. He really enjoys getting them to throw away their medications when they no longer need them, but teaches the role of  food and other simple steps in reversing disease processes. Cleveland Clinic Wellness aims to elevate preventive care and wellness as a core brand of Cleveland Clinic and a core value we teach our patients and employees.

Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry.

My goal has been to lose weight and lower my LDL with weight loss. I had done well initially but struggled more recently. Dr Roizen asked how he could support me. Initially, I responded that I knew what I needed to do but struggled with accountability. He asked again how can he help. I said I could be required to submit my food log to review. I was thinking weekly; he suggested daily. He has review and commented each day. This is definitely going above and beyond. It is clear he cares and wants positive results for me. I am grateful for his encouragement and support.

As I said earlier, my first experience trying to get an video appointment was very, very frustrating! But my video appointment with Dr Roizen was outstanding! I'm still somewhat concerned that I have not heard from the Cleveland Clinic if my insurance will cover the cost of the video appointment and my future in person appointment. I have done everything recommended by CC....Iinking MyChart accounts, contacting my insurance company, & have yet to hear anything back.
