Fire the Asian front desk receptionist,don’t let her ruin your business. The doctors there are fine. Especially doctors Rainbow, she is such a nice person. I don’t understand why she kept this Asian lady front desk for so long even with so many complaints about her on the internet already.

Dr. Charles Lin is absolutely amazing. He is very professional and courteous. He treated me very well, and i felt very comfortable with him. Lot of doctors are so quick to get you in and out, but he was very personable with me, and treated me like a human being rather than another patient. 5 stars!
