Patient Review

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.

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!

Patient Review

I am a dental hygienist and was looking for a dentist who was willing to save my elderly fathers severely broken front tooth. We saw a few general dentists that only gave him the option to pull the tooth and place an implant or a removable prosthesis. I knew of Dr. Weierbach from past family experience and from the dental society. His excellent reputation and many years of experience prompted us to give him a try. I am so glad we made that choice! Dr. Weierbach was able to successfully restore the tooth. In addition, he restored the rest of the front teeth resulting in an improved aesthetic appearance and dental function. It has now been about 2 years, and the teeth are holding strong! Through this experience, Dr. Weierbach has shown that he adheres to a higher skill level of dentistry. Thank you Dr. Weierbach for willing to take on what others would not even consider.

Patient Review

Once upon a time, 25 YEARS AGO... what I dreaded and thought was going to be a nightmare upon the realization I was a candidate for dental implants and crowns, to my complete astonishment turned out to be a most excellent and rewarding experience. From start to finish, Dr. Weierbach treated me with dignity and respect and gave careful thought to the high level of fear and anxiety he knew was within me. Upon my most recent visit this week, I received loud applause for the EXCELLENT, healthy overall condition of my dental work! In all these years I have had NO problems whatsoever. I could not be more pleased and satisfied with Dr. Weierbach and his amazing skill, that has and continues to make a difference in my life! Thank you Dr. Weierbach and kudos to your entire efficient, very capable and friendly staff!
