Patient Review

I wasn't satisfied with my smile from Orthodontia, so I wanted to get some cosmetic touch-ups to correct it. I was recommended to see Dr. Weierbach and I am so glad I did! He was so helpful throughout the entire process and explained each step along the way. The staff was incredibly friendly and made me feel welcome each time I stepped into the office. I love my new smile and am so grateful I had the exceptional Dr. Weierbach to fix it for me! Amanda was also the best and is very skilled at what she does. I couldn’t be more happy with the results.

Patient Review

I needed some serious reconstruction of my front teeth and I wouldn't have trusted anyone else with ensuring that the result looked like my natural smile. Dr. Weierbach is an artist and a wizard. He's so skilled and cares so deeply about the result, it's easy to put your trust in his work. He simply doesn't quit until the result is perfect...and my new smile far far far exceeds anything I could have imagined. Absolutely positively the best dentist I've ever been to!

Having been a patient at many dental practices over the years, I hope this is the last practice. The staff are professional, courteous, and communicate everything with clarity and compassion for a patient's concerns. Best of all, they somehow manage to make a dental appointment fun and interesting.

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% !!
