Patient Review

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!

I definitely would recommend this practice. Before coming here I didn't want to smile. After whitening and crowns I can now smile without embarrassment.

My experience with Dr. Weierbach and staff was awesome. Everyone from scheduling to the hygienists and billing specialists were courteous, competent and professional. The care that Dr. Weierbach shows to his patients is reflected in his entire team. I began wearing dentures a year before my first visit to his office. In October of 2018, he placed 2 lower implants. The comfort, fit and security his new dentures have given me, compared to my old ones, is surprising. I am a very satisfied. confident and grateful customer.

I would highly recommend this practice to all of my friends and family! Dr. Weierbach is an exceptional prosthodonist who truly cares about his patients. I was impressed with the amount of time he took to evaluate my condition and carefully explain the findings and the treatment plan. I needed a difficult bridge that other dentists would not tackle and I am extremely pleased with the results! His entire staff is very friendly and professional.

Not a day goes by that I don’t count my good fortune in becoming Dr. Weierbach’s patient. His excellent work is more evident to me with each year that passes. While an improved appearance is the clear objective, learning about optimum dental heath from Dr. Weierbach and his staff is a valuable benefit that contributes to my quality of life. The results are lasting, and so is my appreciation. Sincere thanks to the entire Weierbach team for your encouragement and ongoing patient education, and for your resolve to achieve the best possible results during my twenty plus years of dental care with you.

I had the best experience with not only the doctor but also with the staff. They all made sure I was comfortable and aware of everything going on. The doctor gives you a step by step of everything and won't be satisfied until your smile is perfect. A total perfectionist in his profession and enjoys seeing his customers happy with the results. You won't be disappointing with his work. When you see the before and after work you will be in shock. Thank You for my new smile.
