What Our Clients Say About Us

After 20 years of fear of everything about dentistry, I was finally referred to Dr. Buza’s office at the end of 2018. I found everyone in his office incredibly kind and compassionate and totally competent. Pat greeted me with her vibrant smile. Dr. Buza and Sabina (his dental assistant)  functioned as a seamless team, making the procedures easy and comfortable. Jen, my hygienist, did a wonderful job and took the extra time to try several different types of dental floss until we found one that did not shred and get stuck in my teeth, making self-care possible. Pam helped me navigate the complexity of the dental insurance world. I feel confident that my future dental care is now in good hands with this wonderful group!”


Dr. Buza- we are so grateful for the wonderful service you and your staff provide. We have had a lot of dental work in our lives and have never been under the care of someone who has the skill and professionalism that you have provided. We trust your guidance and direction. We have always felt that you provide the highest level of integrity and trustworthiness in your practice. We don’t ever sense that you or your staff are pressing for more to be done than what is indicated. When you have cared for my 92 year old mother, you have provided realistic care without adding expensive services that she would probably not live to benefit from. Your staff is helpful in every way and very knowledgeable, from the hygienists to the office and billing support. We are so grateful to have you all as a resource for dental health care. 


Bruce and Melinda B.

One of the most difficult tasks people attempt when permanently relocating across the country is finding high-quality health care.  Fortunately, we found exactly that in the dental practice of Dr. Thomas Buza!  Everyone on staff is highly professional at their craft while also being personally invested in each of their patient clients.  From a simple cleaning to a major procedure, we have been completely satisfied with the superb care we have received, and are happy to highly recommend Dr. Buza and staff without hesitation for any and all of your general dentistry needs!
