Jodi Mathews
RDH

Jodi was raised in Wausau, Wisconsin—so naturally, she loves cheese! Her husband’s career brought them to Virginia, where she earned her Associate of Dental Hygiene from Northern Virginia Community College in 2022. Since then, she’s been a valued member of the Woodside, Sentz & Associates team, certified in nitrous oxide, local anesthesia, and soft tissue laser therapy.

Inspired, she worked as a sterilization technician, attended dental assisting school, and spent five years as a dental assistant before pursuing her true calling in dental hygiene.

Outside the office, Jodi loves spending time with her daughter and two dogs, Macie and Boomer. Whether at home or outdoors, family moments and furry companions are what make her happiest.
