• I had a root canal today. The staff and doctor were very accommodating and professional. I was anxious about not seeing the doctor I had previously seen in this office, my anxiety was short lived after my appointment began. I will definitely recommend Dr. Sullivan to friends and family!
  • Dr. Sullivan. Thank you for your wonderful care of our patients. You have truly removed the fear from the word root canal. A patient this week said 'a root canal with Dr. Sullivan is like water rolling off a ducks back'. It is always a pleasure working with you.
  • I needed an emergency root canal the day before my wedding. Dr. Sullivan and his staff were just amazing. They were beyond kind and got me in and out in less than an hour. I was done in plenty of time to go to my rehearsal dinner. Thank you.
  • Hi Dr. Sullivan. Thank you very much for the amazing job you did and for calling to check on me later. I am doing well, thank you. Please thank your entire staff for me, as they (and yourself) were very considerate and helpful.
