My mom was a patient of Dr. O'Brien. Our first visit was very positive. Dr. O'Brien recommended a possible procedure to help my mom''s congestive heart failure. He informed us that he would review her medical records and get back to us in 2 weeks. We still have not heard back from him and we are going on 5 weeks. Her health condition is critical and Dr. O'Brien is not professional enough to follow up with his patients. We do NOT recommend Dr. O'Brien.

I have known dr. O'Brien. 25 years and he is a very throw and complete doctor. I've been to many other doctors and as far as I'm concerned dr. O'Brien is it one of the best. If not the best. His bedside manner is great but more than that he is a true healer and actually cares about the outcome. If he doesn't call to find out how you're doing one of his staff will. They follow up they make sure that you're doing okay and they ask if you need any help. I have been so happy with dr. O'Brien
