Patient Testimonials

  • I had a major heart attack in 2015. He saved my life. He not only treats his patients, he also teaches them. He took time to explain everything, no matter how many times my children or I asked the same question. He took time to explain in different ways, until we all understood what was happening. He is brilliant and kind. You don't find both of those things in doctors very often. I continue to see him in his office. His staff is friendly and helpful.
