After 20 years in advertising and corporate retail, Hilary took some time off to raise her two daughters. Since returning to the workforce in 2010, Hilary has had a second career focused on customer service.

Hilary does love to garden and went through the Marin Master Gardener program in 2006. She is also a firm believer in giving back to the community and is a weekly volunteer for the Marin Food Bank as well as the Marin Humane Society.
