    How was your appointment with Dr. Marcus?

    Dec 16, 2022
    I literally was dying and knew I had to change Cardiologists. I had cronic AFib and 4 heart ablasions and a mitral valve repair and was not getting any better. I was out of work for 1 year. Working in the hospital field, I saw and heard great reviews about Dr. Marcus. His patients and peers spoke highly of him. I knew he was the one for me. I was able to see Dr. Marcus quickly and he spent so much time with my husband and I explaining what was going on and what needed to be done. He did a Ventricular Ablasion on me and within 2 days I was able to really breathe, no shortness of breath and no heart pounding. I started to get healthy again and become stronger, happy and with a new lease on life. I am now back at work, part time, for now and doing the job again that I loved and missed. So 'THANK YOU'Dr. Marcus for the excellant care, compassion, dignity and the 2nd chance at life you've given me! See you at the next visit!
