"My regular GI at this practice retired, so this was my initial visit with Dr. LAM. I was truly impressed from the beginning. There was a wait from my scheduled appointment time, but well worth the delay. Dr. LAM was professional, caring, and through in her assessment. I felt listened to and was treated with calmness, compassion and respect. I never felt rushed, despite knowing she was running behind schedule and it was close to the end of her day. I never felt she was pushing unnecessary testing or procedures. Her treatment approach was conservative and measured, and she made every effort to include my wishes into planning, considering my previous noncompliance with missed follow-up recommendations. I'm a retired RN with very high expectations for my personal health care providers. Dr. LAM is definitely a 5 STAR+ physician and I highly recommend her."

There were also 2 other Nurses but can't remember their names one in the room and a discharge Nurse who were both excellent.
