    Dr. Gregory McDermott is one of the best medical doctors I've ever received care from. Thanks to his thoroughness very critical incidental findings were found from Pet Scans and treated. He has expertise, patience, attentiveness and I feel privileged to be one of his patients.

    Best Doc ever! Complicated situation going on with me but it is VERY clear he is trying everything possible. Would not go to anyone else.

    This is a relatively new Doctor. I saw my last provider for about twenty years. My new provider needs to take a better, more in-depth look over my medical history if he is going to find out what going on with my health. He is extremely competent and has the knowledge to help me with a diagnosis. I have a complex medical history and he will need all the help he can get. He should use my case in class because two brains are better than one. And many brains together and better than one. I'll be seeing him again in July. He has my confidence.
