Patient Review of Dr. Marc Gerdisch

"Dr. Marc Gerdisch’s bedside manner was impeccable. All of my questions were answered before and after my mitral valve repair."

-- Angie Gregory, Mitral Valve, Valve Repair, 02/10/2012

"Dr. Gerdisch is truly a blessing for cardiac patients. Having had my first stethoscope at the age of 22, I have listened to my mitral valve go from mild to severe murmur over the years.

My first visit gave me confidence that I would be all right by his calm demeanor and confident attitude that he could help me. After my first visit, I felt reassured for the first time that having open heart surgery would truly help preserve my health.

My post-op recovery was amazing having the minimally-invasive port assess surgery. I would have never guessed that 3 days later I would feel good enough to go home.

Even though I was not symptomatic prior to surgery, I feel tremendously better after surgery. My cough that I had for 5 years immediately resolved after my valve repair. It was truly a miracle to listen to my heartbeat normally after years of slowly developing my murmur.

I would highly recommend Dr Gerdisch and his staff, especially nurse practitioner Cindy, for helping me in my recovery. Cindy was amazing in answering my many questions post-op. Even though cardiac surgery is a scary thing, Dr. Gerdisch put me at ease knowing everything is going to be ok."
