Dr. David Cheung is an excellent orthodontist who explains everything thoroughly and with much patience. He listens to you and if you have any questions, he is very patient and more than willing to answer them. He relates well to children/teens and makes them feel important. The entire staff are extremely friendly and accomodating. There were a couple of times we were running late for our appointment and they were very nice about it. I have one child about to get braces taken off and another child who is about to get braces put on. It’s nice that they have their own affordable monthly financing plans as braces can be very expensive. The office on F Street is an older location in old Chula Vista. Quaint, clean and convenient for me. I went to the Fenton Street location in east Chula Vista the other day and that office is more modern and really nice. They are at the F Street location on Mondays and Wednesdays. On Tuesdays and Thursdays they are at the Fenton Street office. Closed on Fridays. I highly recommend this place!
