Fantastic doctor this far. I recommend highly.
It was very helpful, listened to try to figure out what my health problems are that nobody else seems to be able to figure out. And I feel very strongly that he's going to find the answer that I've been looking for.
He's been my doctor for 15 years and always gave me excellent care and advice and recommendations applicable to my unpleasant issues.
Dr. Carolan was great. Was impressed the way he listened to my concerns. Not many do that!
It's very pleasant and willing to listen to anything you want to say, and remark on it with an answer
