Dr. Evan Matthysse

Dr. Evan Matthysse grew up in Pittsburgh, Pennsylvania and attended Penn State University, where he received his undergraduate degree in business. He then headed to NYU for Dental School before completing his year-long General Practice Residency at a practice in the Bronx. Dr. Matthysse proceeded to spend another two years completing a Postdoctoral Implantology Fellowship at NYU and practiced in New York City for over a decade. In 2020, he decided that it was time to make a change and moved out to Austin. He couldn’t be happier.

Dr. Matthysse just recently achieved the FAGD accreditation, one of the highest awards a dentist can receive. An FAGD accreditation requires 500 hours of education after the doctoral degree and residency. Less than 5% of dentists nationwide have accomplished this honor. With his commitment to dental excellence, you can rest assured Dr. Matthysse will provide only the highest quality care for you and your smile.

When Dr. Matthysse isn't living his dream of helping people achieve their ideal smiles, he enjoys reading and staying active. You’ll find him running, lifting weights, paddle boarding, shooting, and even competing in Spartan Races.
