5 out of 5 stars based on 5 Dr. John A. Weierbach reviews.

Patient Review

I am a 3rd year dental student and my experience with Dr. Weierbach was exceptional. I was very selective when choosing a prosthodontist to redo my upper two front teeth. From the minute I walked in his practice, to the day I left with my new highly esthetic and natural looking crowns, I was impressed with Dr. Weierbach and his staff. Dr. Weierbach took the time sit down and to answer any and all questions I had. It was evident that Dr. Weierbach keeps up to date on the most relevant and current research. As a future dentist I would highly recommend Dr. Weierbach.

Not to say everyone will receive dentures for free.But I want to express my heart felt thank you to the Dr and everyone in his office for making me feel so welcome each time I came. I could not eat good food for two years because I did not have dentures but thanks for giving me my smile back.God bless you all.

Patient Review

I had dental implants placed approximately 25 years ago with dental crowns done around the same time. As the years progressed, I was never truly happy with my cosmetic result. I was always aware of my crown imperfections. I guess they were okay at the time but I new they could look better. After months of research on finding a restorative dentist that specialized in dental implant crowns, I made an appointment for a consultation with Dr. Weierbach. Dr. Weierbach and his staff were absolutely awesome. They completely made me feel at ease and explained every step of the process. Months later with numerous visits to his office, I finally got the smile that I set out for. It truly is a game changer and has made me proud to smile again. Thank you for your commitment to excellent customer service and the highest quality of dental implant crowns.

In the beginning I used my dentist of 15 years for my teeth extractions. His services turned out bad. He then recommended me to John A. Weierbach II, DMD (PROSTHODONTIST) and Conestoga Oral Surgery. Dr. Weierbach performed the finishing up of my total restoration. The outcome was great. I fully recommend their services.

I can’t say enough about Dr W. And his staff. I came to them with serious dental issues. He took the time to understand my concerns and worked on not only fixing the problems but making my dental health better. Dr W. gave me a better quality of life that I had thought I would never get to experience. THANK YOU!!!!
