I lost a crown on evening, and although I had to switch dentists a year ago D/T insurance, they got me right in the next day to re-cement my crown! Due to getting it put back in so quickly, I avoided unnecessary pain. Thank you! Sandra H
Very friendly staff and Dr. Guersney is amazing . I called at the last minute and they were able to work me in the schedule. I definitely found my new Dentist. Cindy R
They are the nicest staff. Dr. Guernsey's kind, patient, and cheerful disposition is a wonderful thing to have at the office. He takes the time so you don't feel like a number but a person. Thank you very kindly. rob B
