I had my 1st new patient appointment today at Dr. Thomaszadehs office. From childhood or should I say because of my childhood, I have a great fear of the dentist. Well today that was put to rest. As soon as I walked in,the receptionist was so sweet and welcoming. My dental assistant was Shelby. She was an absolute joy! I felt so relaxed. When I met Dr Thomas she was a breath of fresh air. She is very down to earth and very knowledgeable about all things dental . And of course stunning! I'm so glad I chose Dr. Thomaszadeh and her wonderful crew for all my future dental needs. Sincerely, Terri Donley

First class and professional front office staff and hygienists. The office and exam rooms are spotless and extremely clean and comfortable. Dr Thomaszadeh is friendly, kind, caring and spends time with you to address any concerns or questions you may have.

EVERYONE at this office deserves ALL the gold stars. I have pretty severe dental fears. Whenever I come in the entire staff are so patient and kind. Today, I went in for a crown and was really struggling. Dr. Thomaszadeh was very patient with me and didn't make me feel bad, embarrassed or rushed. I am SO thankful for her thoughtful care. Highly recommend this office.
