TAMI

HYGIENE COORDINATOR
When asked what Tami most likes about her position at Columbia Dental Center, she quickly responds that she “LOVES educating patients especially on care of braces using flossers.” Educating is something she has been doing for 17 years in practice here along with dental assisting, coordinating hygiene and polishing teeth. Tami ensures appointments run smoothly from the time she takes needed x-rays to charting and re-appointing for future visits.

She works on operatory set-up, maintains sterilization of instruments and does maintenance throughout the office. Tami has advanced CPR training as well as training in Sleep Apnea. Outside of the office, Tami can be seen riding in her vintage BMW where she says “convertible hair-don’t care!” As a mom and grandma spending time with family (this includes time spent with her tea- cup yorkie ) is very important to her. When she sits and watches her favorite movie, she is watching “The Notebook”. You may catch Tami eating often at the Cheesecake Factory or in line at Starbucks where she is ordering a white, mocha-latte, no-whip, skim…oh, and a shot of ESPRESSO, please!
