It's been over 10 yrs since I've gotten my braces off and now that it's time for my son to get his, Dr. Cheung is the only Orthodontist I can think of. I've compared experiences and results with friends and I can say my smile has lasted til this day. My friends are now having to go back 5+ yrs later to fix their smiles. Service was always fast and friendly and made it easy for me to keep coming back for each and every visit.
