On 7/9/2026 Giota Lekkas had this to say:
I had a wonderful experience at Dr. Liaros office. From the moment I walked in, the staff made me feel comfortable and genuinely listened to my concerns. The doctor was incredibly knowledgeable, patient, and took the time to explain everything clearly without rushing me. I truly felt understood and cared for, which made a huge difference. I’m very grateful for such a positive experience and would highly recommend this practice to anyone looking for compassionate, professional periodontal care.

On 7/9/2026 Papa Zu had this to say:
I went to Dr. Liaros to resolve oral problems that were a threat to both my oral health and heart health. The office location is very safe. The staff is professional and I experienced excellent communication and timely follow ups and reminders. Dr. Liaros conducted a thorough examination and provided a comprehensive plan of treatment that would resolve my issues. The surgery went very well and was pain free. I was given detailed instructions on post-op care and my recovery went very well. Dr. Liaros called me the day after surgery to check on how I was feeling and if I had any questions. I highly recommend Dr. Liaros and his staff and in fact my wife will be having a procedure done by him in a few weeks.

On 7/4/2026 Barb Busby had this to say:
Dr Liaros is skilled and kind. His staff are great too!

On 6/23/2026 Judy V had this to say:
I had 3 procedures done by Dr. Liaros this past year. He was very professional in planning the care that was needed and considerate in taking the time to communicate his plan. His team made sure that I was pain free during the procedures. Also, his office staff is on top of the billing process and dental insurance issues. I am very pleased with the results and highly recommend their Periodontal care.
