August 6, 2024Mingqi T.Verified patient
Dr. Dang was excellent. His beside manner and ease of conversation was evident and confirmed the reviews that said the same. I wish that his receptionist Yesi was trained to be the same way. She was abrupt and curt in my experience. Her tone of voice in dealing with an adult much older than her was the stereotypical millennial approach, "I know everything and you know nothing." I'm hopeful that her life experiences help her overcome her arrogance and unfriendliness.

Doctor and staff effective for helping the patient and caring about the patient's needs. Very unusual in today's practice of medicine. Understood the needs of Chronic Lyme Disease, which most conventional doctors reject! This doctor and clinic are capable and supportive of addressing the needs of even "challenging" chronic illnesses where UCLA and Mayo can only gaslight their patients.
