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

-- Angie Gregory, heart valve surgery patient

"I have nothing but good things to say about Dr. Marc Gerdisch. I first met him in 2007 after my 1 and only afib experience. After a cardioversion the afib was gone. My cardiologist recommended I at least meet with Dr. Gerdisch because in time he would be fixing my heart. I was sent to talk to him again in early 2018 by my cardiologist Dr. Rao. He was excited that he believed my aortic valve could be repaired and saved by Dr. Gerdisch. We met and came to the conclusion that it was time to replace my aortic root which was now 5.0cm and repair my moderate to severe leaking aortic valve. Dr. Gerdisch has a fantastic bedside manner and is always ready to answer all of my questions. He has a great way of making you feel comfortable. He has done thousands of heart valve surgeries and to me is a pioneer in his field. He did successfully repair and save my aortic valve as well as replacing my aortic root too. After surgery he told me that my valve had no leak anymore. My recovery has been great and I've had little to no pain since I've been home. I had my follow up with Dr. Gerdisch today and he said my echo looks perfect and I have NO leak at my aortic valve and he can no longer even hear a murmur. I'm 1 month out from surgery and can drive and do most things. I'm just starting cardiac rehab to make sure I can be in the best shape as soon as possible. I feel great. Dr. Marc Gerdisch has been nothing short of amazing. I highly recommend him. He has saved my life and I look forward to a long full life to enjoy with my wife and daughter. God Bless you all!"
