About Dr. Gillinov: “My greatest strength as a heart surgeon has two components. First, I can tailor the surgical approach to the patient, ranging from robotic and minimally invasive surgery to standard surgery, using the method that is best and safest. Second, I do this with compassion. In every instance and at every decision, I consider what I would want if I were the patient.”
