Dr. Harmon demonstrates a willingness to be flexible when scheduling patients. She explains what the issue(s) are, provides options and explains procedures to the patients. She gives specialized care and attention to each patient with referrals for dental specialist. During procedures she engages patients to determine levels of pain and discomfort! Dr. Harmon is very compassionate and always maintains a high level of professionalism !

I recently had a chip tooth. The pain. Indescribable. A trusted friend recommend Dr. Harmon from her years at another office. I immediately contacted them. The staff was courteous and responsive. I was able to get an evening appointment very quickly. Transferred my dental records from my previous dentist and received prompt professional service. They are my new dentist. Thanks to the staff! at Trident Dental!
