Dr. Schaffer

"Dr. Schaffer is very well spoken. He really helped me understand everything. Great bedside manners. I'm doing great after 5 weeks recovery."

-- Johnny Wilson, Aortic Valve, Valve Replacement, 02/06/2026

"Dr. Schaffer is the best surgeon I have ever had. I have had multiple major surgeries due to issues from birth, including an open-heart surgery in Houston 7 years ago.

Because of my horrible experience in Houston, I had PTSD and was extremely anxious about the surgery. After meeting with Dr. Schaffer, my fears were removed and I walked out of our consultation with peace and a reassurance that I had found the right surgeon. He never opened my chart, yet who knew everything about my case, including he had contacted Houston to get details on my first open-heart surgery.

My family who attended the appointment with me all commented on how knowledgeable he was on my case and that I was not just another number. I never felt rushed and he took the time to answer all my questions.

My care before the procedure and in the hospital was amazing. His whole staff really cares about you as a patient and ensures that you get the best care while in the hospital. I would highly recommend Dr. Schaffer. In fact, I have already sent two patients to him. My surgery was 4 weeks ago, and I feel amazing and am walking 2 miles a day."
