This dentist is amazing, I have allergies to many medications and had not had dental work in 10 years because of a antaphaltic reaction to dental medication. Dr. Langenbach helped me find something that worked for me, and was not arrogant or condesending about my health difficulties, he is just the best dentist I have been to in 30 years. His staff is amazing, caring, and understanding, what more could you ask for in a dentist?
