Testimonials

On 10/26/2025 Tracy Kamberos had this to say:
Dr. Liaros and his entire team are great. I have had several procedures with them and each time Dr. Liaros has called me the next day to ensure I was doing well. He takes the time to explain the prodcedure so I understood what was happening and even got to see before and after photos. The entire team is nice, caring and professional. Highly recommend Dr. Liaros.

I can’t say enough good things about Dr. Liaros and his staff. As someone who was nervous about getting implants, I was relieved that the entire process was painless and stress-free. Dr. Liaros is not only a talented specialist, but also genuinely caring and reassuring. His staff is warm and efficient, making every visit a positive experience.

This office is GREAT!! The staff is all efficient and friendly. Molly did a very nice job with my cleaning. Dr Liaros is very pleasant and calm. He did a small surgery for me and I felt no pain afterwards. Definitely recommend all of the above.

On 9/25/2025 John Linardakis had this to say:
Aesthetic and clean, state-of-the-art clinic, friendly and professional staff, excellent point of care service! Dr Liaros is very knowledgeable, provided his professional assessment after diagnostic evaluation and educated me on possible alternative next step pathways available for my serious dental concern which was reassuring. I’m glad I called and visited him for a second opinion and his excellent healthcare team! I highly recommend Dr Liaros and his periodontal team! - John L.
