Patient Review

In one office procedure, Dr. Weierbach corrected my dental problem that progressed over decades. In spite of my neglect in dental care, he and his staff were understanding, caring and welcoming. Everyone is impressively talented and the work is artistic. I wholeheartedly recommend this practice. I look forward to the next visit!

Patient Review

I highly recommend this dental practice. I came in with a very serious problem with the condition of my teeth. Dr Weierbach assured me that the dentures he would construct would fit and work well and indeed they absolutely do. I couldn’t be more pleased with the results. If you need a great dentist Dr Weierbach should be your first choice!

I have spent hours in the dental chair for some appointments related to the procedures I am having done. The staff care about your comfort and Dr Weirbach personally calls to follow up. They do not settle for mediocre.
