"My children have been going to Dr. Weiss for 11+ years. He is extremely thorough, meticulous, responsive, and kind in the treatment of his patients. We travel close to a half an hour to get to his practice but I wouldn?t have it any other way. My son, Matt had multiple allergy issues, missed countless days of school. Dr. Weiss determined the issues treated them, made a referral to another reputable doctor for another specific issue and Matt is now a healthy, happy 18 year old. One time in the past, Matt had to be rushed to the E.R. and Dr. Weiss was right there waiting for him! I have and will continue to highly recommend Dr. Weiss to whomever I know. "
