Unfortunately, after 3 years our family will not be returning to this office. While Dr. Shim may be an good dentist, his office is a mess. There is one good hygienist left (Shannon). The others are awful. The assistant said she cleaned my son's teeth, she did not. When I asked why they were billing insurance for a service that was not provided, she was not truthful. I receive "bills" for a service from 6 months ago after paying the requested co-pay. There appears to be very high turn over. It is a shame. When we started with Dr. Shim we were very pleased. It's too bad.
