  • Dentists on the Square provides excellent care. For over a year, I have relied on them for everything: cleaning, a crown, and even an extraction. I have never liked going to dentists, but in DOTS I have found a dental office I actually enjoy visiting. Dr. Tewari and the entire DOTS staff are friendly, professional, and welcoming — most of all, they do awesome work!

  • I highly recommend! The staff is really friendly and nice. I had my wisdom teeth removed by Dr. Roberts and Vince and they are great. I was really nervous to have that type of treatment but they reassured me that I would be okay and made it a good experience. It is so worth it!
