Knows what he is doing. Expects his patients to follow his orders in order for the patient to get help. He knows anything and everything there is about endocrinology. The first time I went to see him about my problem, when no other doctor could figure it out, he knew exactly what was wrong with the symptoms I gave him. I had been to numerous MD's for 7-8 years and no one knew what was wrong until I was given the opportunity to see Dr. George McLean. He expects you to do what you need to do to help your self with your problem whatever it is such as take your medications, treatments, etc. He saved my life and I am forever grateful. Thank your Dr. George McLean. In order to get well or better you need to follow his expertise and knowledge.. He knows what is talking about.
