    I visited this dental office for tooth pain based on my daughter’s recommendation, and I’m so glad I did. The doctor examined my teeth thoroughly and clearly explained my options, including an implant or extraction. I’ve never had a dentist who was this professional, patient, and detailed. He took the time to make sure I fully understood every step of the process. The customer service here is excellent as well, everyone was kind, helpful, and welcoming. I’ll definitely be recommending this place to my family and friends.

    I have been a patient of Dr. O'Connor for over 25 years. He has lots of experience and gives great attention to detail. He is unfailingly kind and always goes the extra mile, which I can say for all the staff as well.

    Best dentist doctors in town. The staff is also great, especially Tricia. We love the family atmosphere they create at this place. Love it!

    I have consistently found Dr. O’Connor and his staff to be caring and professional. I do not feel like they try to upsell procedures to me. When I recently experienced a toothache, they were able to see me the same day. Overall, I have been pleased with the care I have received at this office.
