Addison Manion
Dental Assistant

Addison received her Dental Assistant Certificate from Keystone Dental in 2016. She finds joy daily in helping patients smile and enriching their lives. It is important to her that patients realize that dentist offices don't have to be scary.

When she isn't assisting Dr. Matthes, you'll find Addison outdoors fishing, boating, hiking and camping. She enjoys the company of family and friends, as well as volunteering in the community. 

Teresa Fradet
Dental Hygienist 

Teresa has been a hygienist for 18 years and counting. She loves getting to know and caring for each patient individually. It's important to Teresa that each patient feels comfortable while they are at the office. She loves being part of a knowlegable staff that truly cares about all the patients and providing education on oral health.

In her spare time you can find Teresa gardening and finding new ways to cook with what she has grown. She loves fishing and attending sporting events with friends and family. She has two dogs, Charlie and Piper, and her cat Chopper (who often thinks he is a dog himself).
