My passion is advocating for children and families of the foster care system. It has led me to take many speaking engagements and craft several pieces of child welfare legislation. I would not change anything, except for needing a beautiful smile to complement my drive, passions and personality. Dr Weierbach and his team have given me that smile. I now have confidence that no matter what situation I am in, my smile will properly reflect my personality and professionalism. Dr Weierbach and his team are like a big family and make you feel right at home from the first visit through the entire process. I cannot say enough about how well the staff came together to achieve the best results for me. It has truly been a great experience and exactly the outcome I was looking for. Thank you, Dr. Weierbach and the entire team for my wonderful smile. Garry Krentz, President PA Child York, PA

When it was the time for me to choose a dentist to have implants, there was never a doubt who I would choose! Trust is the word to describe Dr. Weierbach and his Staff. I traveled from Florida to Lancaster just so I could have Dr. Weierbach as my prosthodontist. Special Thanks to Chelsee, Amanda, Melissa, Sherry, Susan, Jennifer, and Gretchen.

Excellent staff and very accommodating. I had a big event coming and wanted some cosmetic work done last minute. Not only did Dr. Weierbach make time to see me and the procedure, his assistant Chelsee came in on her day off to help. I have the smile I always wanted and could not be happier. Thank you!!

I was referred to Dr. Weierbach for a sleep apnea mouth guard. Everyone in the office was very friendly. They took the time to explain how the device worked and answered my questions well. It's been so nice to be able to sleep without a c-pap!
