Greg Wagner

In February 2024, Greg Wagner was sworn in for a 10-year term as the Controller for the City and County of San Francisco. Greg succeeded Ben Rosenfield, who served as Controller for 16 years. 

Greg began his career with the City in the Mayor’s Budget Office from 2006 to 2011, serving as Mayor’s Budget Director under Mayors Gavin Newsom and Ed Lee. As the Mayor’s Budget Director, Greg led the development and approval of the City’s annual balanced budget through the financially challenging years following the Great Recession.

Prior to becoming Controller, Greg served the San Francisco Department of Public Health (SFPDH) as Chief Financial Officer where he managed a multibillion-dollar budget, and then as Chief Operating Officer of SFDPH where he oversaw the finances and administrative operations of the City’s largest department, including Zuckerberg San Francisco General Hospital (ZSFG), Laguna Honda Hospital, and a citywide network of primary care, mental health, and substance use programs. As both Chief Operating Officer and Chief Financial Officer of SFDPH, Greg was crucial in the financial management of key public health and citywide priorities over the last decade, including San Francisco’s emergency response to the COVID-19 pandemic. He was fundamental in managing the capital program to rebuild ZSFG and multiple outpatient service sites, the implementation of Mental Health SF, and the City’s implementation of the Affordable Care Act.

Now, as the City's chief financial officer and auditor, Controller Wagner, with the support of his team, is responsible for governance and conduct of key aspects of the City's financial operations, including processing payroll for all City employees, managing the City's bonds and debt portfolio, and processing and monitoring the City's budget. His office is also responsible for providing policy and economic analyses, estimating the cost of ballot measures, administering the City’s Whistleblower Program, and directing performance and financial audits of City activities.

Greg earned his Master’s degree in Public Policy from the Goldman School of Public Policy at the University of California, Berkeley. He lives in San Francisco with his wife and two children.
