Dr.Mayer has been my surgeon for all of my cardiac operations(4). My most recent one and the one i remember having the most interactions with him was when i was 22. He explained everything thoroughly and answered any questions me or my family had. He was knowledgeable yet used language I could understand. The most amazing part to me was after my surgery was complete he stayed with me, he was with me a total of 14 hours. This shows his dedication and love for his job. I would 100% recommend him
