Dr. Lah has always been friendly and courteous. Very professional but not unapproachable. I was very scared with my medical condition when I was first introduced to him but he has always made me feel at ease and I feel I can ask him questions and he takes the time to think and answer them. I have already recommended him as a doctor to my friends and would do so anytime.

From the receptionist to the the gentleman that rolled me out to my car, the entire staff was warm kind professional and friendly. Even the nurse who initially called me with details for my pre procedure prep was so accommodating. She answered every question with such patience.

Professional, and knowable Doctor. Staff members are the best. They make you feel like you matter. Not just another person to get through the door. I've been to many of those clinics. Thankfully PIH has no such attitude.
