I have been going to Dental Associates my whole life and the staff are amazing! They are phenomenal with my young child and are super patient, nice, & caring. They do a wonderful job caring about our dental health. We see Dr Collier (Dr Goettch was my original dentist but has since retired) and they are wonderful dentists! The hygienists are spectacular and very nice! Overall I have always had great experiences.
