Dr. John A. Weierbach- Retired
Genetti Prosthodontics (formerly Weierbach & Genetti Prosthodontics) began as Weierbach Prosthodontics, founded by Dr. John A. Weierbach in 1989. Over the past several decades, the office has become known for comprehensive prosthodontic, implant, and restorative care grounded in clinical excellence, compassion, and long-standing patient relationships.
John A. Weierbach, DMD practiced for more than 30 years in clinical dentistry. This experience and the recognition of his peers set Dr. Weierbach apart in the ADA community. His extensive educational pursuits, constant review of the latest technologies, and lengthy tenure of more than three decades delivering aesthetic and functional results contributed to the solid reputation of his prosthodontic practice.
Dr. Weierbach is a graduate of Bucknell University and the University of Pennsylvania School of Dental Medicine, where he earned his Doctor of Dental Medicine degree and General Practice Residency Certificate. His Prosthodontic Specialty Certificate was awarded by Temple University Dental School.
Dr. Weierbach served as one of the pioneering teams trained in the technique of Teeth in an Hour, the innovative process for one-visit implant restorations (see Implant Dentistry section). Dr. Weierbach mentors senior dental students in clinical dentistry at the University of Pennsylvania School of Dental Medicine. He also lectured extensively to dental colleagues on implant, cosmetic, and reconstructive dentistry.
Dr. Weierbach leads a local Spear Study Club, dentistry’s leading provider in continuing education for clinical expertise. The practice was also cited as a favorite of Lancaster County Magazine readers, featured in the magazine’s Makeover issue, and was featured on the cover of Lancaster County Magazine for the practice’s exceptional contribution to restoring confidence and quality of life through smile design highlighting the journeys of several patients.
Dr. Weierbach and his wife, Kathy, enjoy an active role in their community together with their three children.

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!

Honestly, could not have asked for a better experience. I am more than pleased with their service and the end product. There's a reason I was the 3rd family member to get dental work done there, it's because you guys are the best!

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.
