    First thing I want to say is I am scared of dentists!! I go to all my cleanings hoping nothing is wrong; if there is I put off going as long as possible because I am too afraid. But then I found Smiles Unlimited!!! Everyone here listens and understands how I feel and does everything in their power to help me through whatever I am having done, especially Dr. McNamara. Because I am so nervous, I salivate like crazy and feel like I am drowning. Dr. McNamara lets me signal him when I need suction!! I have not been taken seriously at prior dentists and I panicked, feeling like I was drowning.

    Hanna and Cathy treat me like family. I actually enjoy going to the dentist now!! I have even referred my husband, daughter, son-in-law, and even my 4 year old granddaughter.

    I am 80 years old and have a beautiful, natural smile thanks to Dr. McNamara and his staff.

    Dr. McNamara has been my dentist since 1994. I feel very comfortable when visiting the dental office. The staff is very professional, courteous, and concerned for the patients comfort.
