Dr G. In my humble opinion IS THE ABSOLUTE BEST Cardiologist. I've had 3 prior to seeing him, and by far THE BEST at making me feel comfortable, he is VERY informative, appears to be concerned about the state of my health, he includes/accepts my opinions about procedures and treatment, I feel a part of my treatment he is most definitely unlike ANY other doctor I have ever seen.
