Her clients include businesses of all sizes from the growing food business to multi-generational wineries and vineyard management companies.

Loving helping individuals and families, she provides full spectrum of advice to her clients enabling local clients to meet their goals be it building a business or maximizing their estates for future generations.

Having been involved in complex litigation for thirteen years including the top real estate jury verdict in the state for 2014, she counsels clients on the issues faced there.

Desiring to preserve Sonoma’s historic nature, she serves on the board of the Sonoma Valley League for Historic Preservation.  Committed to children’s issues locally and internationally, she has been on the boards of the Kenwood Education Foundation and the Ama Foundation. She has served on the Sonoma Community Service and Environment Commission as well as the board of the Sonoma Valley Mother’s Club.

An Alum of the Governor Gray Davis Administration, she aided the First Lady. She earned degrees from UC Davis and USF School of Law.  During law school, she clerked at Cotchett, Pitre & Simon (now Cotchette, Pitre & McCarthy).  In her spare time, she lobbied successfully for policies affecting the rights of children at the UN Women’s Commission.

She was the first lawyer to be named a Sonoma Star by Valley of the Moon Magazine, naming her as one in 2018, preceded by North Bay Business Journal’s naming her One to Watch in 2017.

She feels blessed to call Sonoma Valley home, where she lives with her two sons and daughter, rescue pup and pet tortoise.
