Welcome to the website of SmileDoctors: Dr. Jim Der and Dr. Lonny Lee

Our mission is to provide quality, convenient dentistry in a caring environment. We are open evenings and weekends to accommodate your busy schedule. We have two convenient locations to serve you:

If you are anxious and afraid of dentistry you have found the right office. We offer sedation and nitrous oxide at our new Marine Way Dental Centre.

Dr. Der and Dr. Lee can provide quality dentistry in an anxiety-free environment. With sedation dentistry, you'll feel relaxed during your appointments. It's almost as if you were asleep during your dental visit.
