Dr. Shah is located just North of Huntington Dr in Duarte, CA on Buena Vista St. He is a good Doctor, but his office is quite small and is always crowded. It's as though the office schedules appointments for the same time and you wind up waiting to been seen. There have been occassions that I have waited up to an hour just to be admitted into a room and then have had to wait more time to be seen. It's not the most upbeat office, but the staff is kind. They do accept Medi-cal, that may be why there is always a wait and he's over booked. But he's always willing to fit you into his schedule. If possible, makes appointments right when they get back from lunch or the end of the day. That's when it's usually died down and quiet in the office and you're seen without too long of a wait.
