Dr. Byrne and his staff are great. I have had many experiences including surgeries and in 2007 he and his associate Dr. Thomas installed a very large stent from the main arteries in my legs up to my lower aorta as it leaves my heart. He has also done a number of tests, anagrams and one stent near my heart that had a blockage. With out him I would no be here.

Dr Byrne is the model physician; professional, confident, sociable, and exceedingly knowledgeable regarding his field of practice. His surgical skills are exceptional and designed to accomplish the needed medical intervention in a manner that results in the least discomfort possible for the patient. His leadership among the other physicians in his cardiology treatment group is obvious.

Dr Byrne historically runs late. I understand that and know that he will spend as much time as is necessary with each of his patients, including me when he gets to me. He is worth the wait. often, I will be offered the option of seeing a Pa/NP and I can decide whether I want to wait to see him or not.

I have a complicated health history and have seen many, many doctors. It is very difficult to find a doctor, let alone staff, that seem to honestly care about you and listen when you talk. I always feel heard and cared about by Dr. Byrne and his staff. I wish he were my primary. He's a great doctor.
