Dr Brown replaced my husband's aortic valve and did one bypass. From the beginning Dr Brown was clear, concise, and put us completely at ease. All of my husband's doctors were impressed with his work when they saw him post surgery. His office was exceptional as well. I had questions and emailed his nurse who promptly answered everything I needed to know and filled out paperwork I needed in a matter of days. I would recommend Dr Brown and his staff unequivocally.

It has taken me over 3 years to get over the horrible experience my family had with this surgeon and his medical staff. I am finally ready to give my review. I wouldn't recommend this surgeon, or the Gagnon Cardiovascular Institute to anyone I truly love and care for. If I could give 0 stars, I would. My father had to get a valve replaced and not only was the valve put on wrong(it now leaks), they caused an aortic dissection while replacing the valve. My father also suffered a stroke when he woke up from surgery. The way this surgeon treated us after the surgery was down right insulting and he never bothered to visit my father after either. I could go on and on about this but it's no longer worth my time. Luckily my father is a very healthy and fit man and he survived, but it definitely wasn't because of this surgeon or hospital.

Dr Brown just recently performed a double bypass surgery on my heart and literally saved my life. I highly recommend Dr Brown for any surgery needs you may have.

Dr Brown repaired my mitral valve in Sept 22. You can tell right from the first consult that Dr Brown is a pro. Very clear & thorough. The operation was a success and everything was spot on after the surgery too. The office staff was great too with any follow up questions and exams. I've run into many people who've had surgery by Dr Brown and they all are thankful that they got lucky enough to have had Dr Brown as their surgeon. When I've spoken to other doctors (no matter if the are heart dr's or not), they all know Dr Brown and say that he is the best. That speaks for itself!! There are heart surgeons and then there is Dr Brown!! the best around!!!
