Bonnie Christopherson, Kathy Hagan, and Chanette Marquart serve as our trained and very capable dental assisting staff.

Tressa Wang is our front office manager and receptionist. She serves the clinic with extensive background in medical insurance and computer technology. Tressa is a real ‘people person’ and she will always greet you with a welcome smile!

The entire staff is required to stay current in cardiopulmonary resuscitation and each of them takes frequent continuing education courses to stay updated on the most modern dental protocol. Just one of our recurring continuing education concerns is the matter of infection control and disease transmission.

The staff at Sheridan Dental Clinic is committed to the highest standards as set forth by the American Dental Association when it comes to the safety of their patients.
