"Dr. Pak is an outstanding doctor. When she examined me on a previous appointment she noted an extra heart beat and recommended I get an EKG. After the EKG, I had a nuclear stress test which noted a blockage in one of the arteries of the heart. Turns out I needed 2 stents put in mu heart artery by my cardiologist. I was informed I had an 80% blockage in that artery. I believe that because of Dr. Pak's concern she quite possibly saved my life. I can't express how thankful I am."
