Wonderful visit with Dr. Gillinov! He is very down to earth, considerate and caring. He took his time to explain every aspect of my mitral valve repair surgery with me, even the things I hadn't even thought of, and kindly answered all the questions my son and I had. He treated me like his own family member, and set my mind at ease. I feel very blessed and fortunate that Dr. Gillinov will be performing my surgery, and I would highly recommend him!
