I have been to MANY dentists, periodontist and surgeons over the years. Thus office, doctor and staff are by far the best ! The attention to detail, the state of the art equipment and the atmosphere of this office are all a 10+! Just had a crown put on (I have several from previous dentist) it looks and feels EXACTLY like my tooth! Shape, color match and feel! I left feeling like I was at the dentist of the rock stars!

The full staff at Weierbach is outstanding, from how you are greeted to how you are served. Everyone goes the extra mile to make you feel comfortable and put you at ease no matter the reason for your appointment. Following any major procedure, Dr. Weierbach personally follows up to confirm how you are feeling and make sure there is no additional follow-up needed.

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.
