I had been to 4 doctors for my A-fib. They didn't know how to help. Then I was able to get onto Best Doctors and found Dr. Walter Kerwin. He saved my life three times. First with a pill that gave me a year to no A-fib. Then a cryoablationn that worked for four years and then another one that sent it away. I would not be alive without him. He and his staff are also very kind.
