Patient Reviews
Oct 27, 2021
Dr Grehan is an excellent surgeon, very knowledgeable and has a great bedside manner. He always answers any questions you have. He did my mitral valve repair and one bypass. He told me everything up front and took the time to figure out exactly what I needed and when. He made me stay one day longer in the hospital which wasn't received well at the time but it was the best thing for me and sped up my recovery. He really knows hearts. My wife is so happy because I will live a lot longer due to Dr Grehan's skill and knowledge.
