What Our Patients Say
  • You are a top-notch dental practice! I have been to several in my lifetime and yours tops the list of professional services, timeliness of appointments and a wonderful staff! I have found your business runs like a well-oiled machine which I do appreciate. Many thanks to Dr. Weir, Dr. Thomas and your kind and caring staff.
    Ginni P.
    No issues, just accolades! Everything went very well and was particularly impressed at your attention to customer service. Both dentist and DA explained what they were doing at every step of the way, I got full answers to all of my questions. You seem to have the needs of the patient at the heart of everything you do!
    Phil W.
  • The staff was great during the procedure. Having wisdom teeth extracted was a bit distressing but confidence of staff helped me get through the process and have had very little pain afterwards. Great job team Thomas!!!
    Brett K.
    As with previous visits, this one was smooth and efficient. The technician answered my questions about whitening my teeth and was very thoughtful and friendly. I would, and have, recommended your practice to friends and co-workers.
  • We usually see Dr. Weir and this was our first time seeing Dr. Thomas, but he was great as well. Ms. Holly is the greatest, especially with kids. I used to have a major fear of going to the dentist and now it's kind of a nice thing to do. Thank you all!
    Very professional and courteous staff. Clean office, thorough work, and wonderful patient care. I feel very confident with the knowledge and expertise of Dr. Weir and would highly recommend his services. Top notch support staff.
