    Dr. Barth is fantastic. He is very knowledgeable, explains things very clearly, and he clearly cares about his patients. I saw him previously for atrial fibrillation. We had many office visits while managing it, and he performed cardiac ablation, as well. I trust him and was happy he was able to see me and give me guidance. I highly recommend him!
