Patient Review

I accompanied my father to his visits throughout the course of his dental implant journey. Dr. Weierbach took great care to explain all of our available options and how each process would work. Ultimately, we chose fixed implants and are incredibly happy with that decision. The staff was amazing and really took the time to make us feel comfortable and informed along the way. From check-in to check-out, the team at Weierbach & Genetti made it a personal experience and my father never felt like “just another patient.” Most importantly, the implants turned out great! I highly recommend Dr. Weierbach and team for dental implant needs.

I cannot recommend Dr Weierbach enough!! The staff at the office are all soooo kind and friendly. Everyone went above and beyond to help me and welcome me to the office. Dr Weierbach helped treat a TMJ issue that was leaving me in discomfort daily. After one visit to the office I truly feel like my life has changed! I do not have that daily discomfort and am so thankful for Dr Weierbach and his staff. Very appreciative for all they have done for me!

I love connecting with people and have found there’s absolutely no better way to instantly do so than by flashing a fabulous smile. An abundance of gratitude to the genius and superb prosthodontics talents of Dr. John Weierbach and his cohesive team. They embraced me as family and I felt like I was the most important patient whenever I was in their presence. As a woman with a passion for fashion and accessories, I can tell you that there’s no better accessory than a stunning smile. Thank you to Dr Weierbach and his team for the unique skill sets they bring to the treatment process. Antionette (Toni) Sabatine-Schreder Lancaster, PA
