Dr. John A. Weierbach- Retired

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.

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 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.

Patient Review
I met Dr. Weierbach when I was 18 years old, and a pre-dental college student. Today, I am 23 and will be starting dental school in a couple of weeks! Without a doubt, Dr. Weierbach has been the most positive influence in my journey and truly a mentor figure. Of all the dental professionals I have shadowed in Lancaster, I could quickly tell he not only LOVES what he does, but he also EXCELS at it. He is patient, fair, compassionate, knowledgeable, enthusiastic, intelligent, talented, and someone who values both learning and teaching. In his office, I am never a "shadow," but someone he sees potential in and wants to share his craft with, even taking the time to introduce me to his patients and to talk about life over lunch. I have been thankful for the opportunity to sit in on his courses at Penn Dental as his guest, and to learn about his own mentors and journey into dentistry. Every member of his staff is also a gem. They are professional, invested in their work, genuine, caring, and the best at what they do. They have become another family of mine that I make sure to catch up with and visit whenever I am home over breaks. I feel lucky to have Dr. Weierbach in my life as someone I look up to in all the roles he holds, and can trust with my dental health. He is truly inspirational, and his office and staff are exceptional.

I have been a patient of Dr. Weierbach for over two years being treated with a mouth appliance for sleep apnea. Dr. Weierbach and his staff are so welcoming, friendly, and professional. The office is attractive and very clean. I feel very comfortable when I walk through the door being greeted by the friendly staff. My mouth appliance works very well and it is comfortable to wear all night. I highly recommend Dr. Weierbach to anyone who is searching for a wonderful specialty dentist. You will not be disappointed!

As always, my recent experience with Weierbach Prosthodontics was excellent. Dr. Weierbach advised me of options for addressing my situation so I could make an informed decision. He and his staff met all expectations for eliminating the risk of further chipping and restoring my upper front teeth with veneers of the right shape, size and color. If your smile deserves the work of a skilled artist in a relaxing, pleasant setting, then Weierbach Prosthodontics is the place for you.

From the moment I walked in the door... I was impressed... The waiting room is cozy and a beautiful floral arrangement greets you upon entering. The front desk receptionist was very friendly and had a big welcoming smile! My hygienist was absolutely lovely... She has a great sense of humor and put my mind at ease immediately... Answered all my questions and did a fantastic job! The doctor was also friendly and was quite amusing as well! Overall this was without a doubt the most pleasant experience I have ever had at the dentist.. I highly recommend this office!
