Amy Costa

Amy Costa is a public policy, public affairs, and organizational strategist with over two decades of experience in an array of senior strategic and executive roles. Costa’s experience includes serving as top leadership at the highest levels of California government, leading public affairs strategy for one of Californian’s largest employers, teaching and coaching organizational decision-making for Fortune 100 companies, overseeing public affairs strategies for one of the world’s largest higher education systems, and working as the Deputy County Administrator of Alameda County.

Over the course of her career in public service, after specializing in education policy, Amy became a utility player in the many policy areas across the state budget. Amy served as part of the negotiation team for Governor Brown on extending the State’s cap and trade program. She served as the lead for Senate Democrats on an education GO bond. Costa also led on the first major state investment in California history in homelessness with the creation of the Homeless Emergency Aid Program. She has been involved in a number of ground-breaking higher education policies including the Associate Degree for Transfer and the Student-Centered Funding Formula for California community colleges. As part of the 2022-23 State Budget, Amy helped several clients secure funding including a $500 million appropriation for a capital project.  In the 2023-24 State Budget, Amy secured $73 million in line-items for clients and helped secure a $4.8 million grant.  

Costa left public service in 2021 to open Full Moon Strategies so she could use her unique experience solving complex public policy problems from many different vantage points to help her clients achieve their objectives. Costa says the best strategies start early and get the government working to resolve problems before it starts creating them.

Amy is a proud mother of three and an alumna of Saint Mary’s College of California.
