SACRAMENTO – Diane Griffiths, who has served as chief of staff for Sen. Bob Hertzberg, D-Van Nuys, since he was elected to the Senate in 2014 and previously when he was Assembly Speaker, is retiring today, ending a public service career that has spanned four decades. 

“Diane is the consummate chief of staff, and I will miss her dearly,” Hertzberg said. “She has been invaluable in keeping me and my staff on track and helping us to be as effective as possible. I wish her all the best in her retirement, and I thank her for her incredible and outstanding public service over the years. Happily, she has agreed to help me out during the transition and will continue working on selected issues.”

Previously, Griffiths served as chief of staff to the University of California Board of Regents and General Counsel to the Fair Political Practices Commission. She has worked in the Legislature in many different roles and handled a broad range of policy, legal and administrative issues. A graduate of UC Berkeley’s Boalt Hall School of Law, she clerked for the California and Alaska Supreme Courts after graduation.

Bedard previously worked as legislative director for former Assemblymember Nancy Skinner. In 2010, he was selected for the California Council on Science and Technology’s science policy fellowship.

Before coming to work for the California Legislature, Bedard worked at the University of Texas at Austin on renewable energy materials. He received his Ph.D. in 2006 from UCLA in theoretical physical chemistry.
