  • "Julie has been my hygienist for 40+ years I will miss her, she's been great. Dr. Buck and his father before him have always been so nice, professional and most importantly they make sure your comfortable. Dr. Buck always makes sure you don't feel anything if your getting any work done, which I appreciate. I guess I'm wimpy when it comes to pain in my mouth."

  • "Where to begin? Dr. Brust has been my dentist for almost 30 years now! Him and his assistant make the best team. Absolutely enjoy my visits to Heritage Dental. I feel as if I were part of the team and not a costumer when I go in. My daughter’s absolutely love going to get their teeth polished as well!! Hygienist Ana and Bobbi do an excellent job taking care of my girls! I don’t think I could ever switch dental offices. Thank you for all you do at Heritage Dental!"
