TI have always had a dentist phobia, but not so much any more! I know I am well taken care of and have the most up-to-date technology in my care. Dr. Call and Dr. Hamann are both very caring dentists, and they and their entire staff make sure you are comfortable at all times and informed in the procedures they are doing for you. Super friendly all around. Finally have a smile I can be proud of! Love this place!

I started goon to this going to this practice when I was about 10 years old in 1948 when Dr. Fields was just starting out. It has been and continues to be the best dental practice. I feel very fortunate to have Dr. Hamann and her staff take care of our dental health. Now my husband and sister are patients too. Smiles to you all!!
