Meredith grew up in Petaluma and remains in Sonoma County, currently residing in Windsor.

“I love Sonoma County and small town living,” she affirms.


Meredith particularly enjoys being active and spending her spare time with family and

friends outdoors. She participates in ‘Soccer Sundays’ every week with either indoor

or outdoor leagues year-round. If it’s not soccer, then it’s a run or bike through town or

at various race events. Now and then, you can spot her hitting the county parks for a

little geocaching.


Meredith admits she just learned how to swim a few years ago. “I was encouraged to

try a triathlon and, even though I didn't know how to swim, I signed up,” she confesses.

Meredith had just six weeks to learn how to go from swimming a half-lap to a half-mile!

“I certainly wasn't the fastest, but I did it!” Additionally, not many know that Meredith

was a teen mom. “Going from teen mom to accounting professional is a pretty

awesome achievement. I think my achievement demonstrates my tenacity and determination

to work hard,” she expresses. Her current motto is: “Work hard, play harder!” 


Meredith greatly values her time spent out of the office as well as her focused career efforts.

Being an engaged parent, an active member in her community, and chronic volunteer

are top priorities for her, which she also finds quite rewarding. Meredith supports

many charities in the spirit of raising awareness and to support fundraising to find a

cure. She often runs or bikes for charities in honor of her dear family and friends. 

Some of the organizations and/or events include: Avon 39 - Walk for Breast Cancer,

American Diabetes Tour de Cure, Walk MS, Autism Speaks, North Bay Down Syndrome

Association, American Heart Walk, and Sonoma County Human Race… just to name a few.


Meredith also holds current volunteer/board positions with the Town of Windsor as the Parks and Recreation Commissioner and with Charles M. Schulz Museum & Research Center as an Audit Committee Member. Some of her past volunteer board positions included working with the Extended Childcare Coalition as a board member (15 years), as the Windsor Schools PTA Secretary (2 years), and the Golden State Land Conservancy (7 years).
