Dr. Felder has taken care of my mouth for 15 years. She is one of the great secret assets of our community. Unfortunately, she suffers from Carpal-tunnel syndrome and has had to retire from the practice of dentistry. The new dentist, Dr. Ngyuen, is also an excellent practitioner, and he is very young and energetic. I have had one root canal, followed by a crown, by him, and found it to be painless and very low in stress.
