Thank you, thank you, thank you DR WEIERBACH !! You are the best at what you do. Thank you to him and his team I can now smile with confidence! I went in to his office with panic towards dentist because of what happened to my mom. I was terrified. Thankfully my daughter found him and I have zero regrets. He transformed my mouth! I got implants and veneers. He explained everything in detail and cost of procedure. Everything was clear from start to finish. I couldn’t be happier with my results. I can’t wait to show my family in Puerto Rico !! Thank you again Dr Weierbach !! I recommend 100000% !!

Patient Review
I had a terrible overbite and ground my teeth. My regular dentist of many years told me that my teeth would eventually break and he said "I have no idea how they will fix this." Well, they started to break and he referred me to Dr. Weirbach. Over a three year period, during COVID, I had several extractions, several implants and crowns on all my teeth to correct my bite. He is very meticulous and talented. He and his staff (both professional and office) are extremely caring and helpful. I am so looking forward to eating corn on the cob this summer, for the first time in 3 years!

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.
