I had been diagnosed with Atrial Fibrillation that was discovered during a stress test. Dr Onufer performed an Ablation for me on 11/16/22, the surgery went well with no complications. He is extremely knowledgeable and his bed side manner is the best that I have ever experienced. I would highy recommend him and his staff, I think that he is the absoulute best. We are very fortunate to have such and outstanding cardiovascular surgeon in our area.
