About US

Starting small, Anderson & Zentz Dental has been able to tailor the practice to best suit the needs of our patients over the past decade. Starting in 2008, he incorporated CEREC® technology, which allows for porcelain crowns to be completed in one visit. In 2009, Dr. Anderson began placing implants. In 2010, due to the tremendous growth of the practice and constraints of the original office location, Dr. Anderson moved the practice to its current location.  In 2012, Dr. Lee joined the team part time, and in 2014 Dr. Zentz joined the practice and is now a full-time partner in the practice.  Thanks to many hours Dr. Anderson and Dr. Zentz invest each year in continuing education, we are able to offer to our patient’s same day crowns (CEREC®), implants, implant dentures, periodontal surgery, oral surgery, clear braces and more.
