      "For 10 years I was sick, visiting specialist after specialist, to no avail. Then I met Dr. Weiss, who was patient, kind and determined to cure me. And he did! For the past 7 years, Dr. Weiss and his amazing colleagues are the only specialists I go to. Driving 1.5 hours just for a visit is worth every second when you see doctors who really care about you. I have referred several people to Weiss Medical, and they have been cured!"
