Dr. Tan is by far the best OB-GYN I've ever had. He really listens and makes you feel respected. His kindness and bedside manner instantly put you at ease, and his exams are so gentle. I used to dread my Pap smears because they were always painful, but with him, that's no longer the case. I'm truly grateful to have found such a caring doctor.
