My procedure was a journey and everyone in the office was there for me the whole way through. They were encouraging, held my hand when I needed it. They explained everything so that I understood what was needed and all the steps to get to my final, wonderful results.

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.

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.
