I agree with Veronika O. Dr Teng's office manager/sister is the nasiest, rudest and most arrogant person I've dealt with in the medical field. It's amazing he still has a practice with the way his office is run. Even the staff at Mountainview Hospital don't want to deal with her. When I had surgery there and they needed a form from his office, they asked me to call because they didn't want to deal with her. i also told my family Dr never to refer him again. There are other surgeons, find someone else.
