Patients are de-identified for confidentiality and patient privacy.October 16, 2024SUGAR HOUSE HEALTH CENTEROne of the best doctors I've ever had. Extremely intelligent, amazing bedside manner. Gives me all the medical information I need to make the best decision for me and my health, and then genuinely and fully supports the decision he's empowered me to make for my body.
September 19, 2024SUGAR HOUSE HEALTH CENTERVery approachable physician, great bedside manner. He shakes hands at the beginning and end of appointments which I like. He spends a lot of time with patients. The wait can be long, but it's because he spends a lot of time with patients.
