Mary Hall is the elected Auditor in Thurston County (WA). She is a certified elections administrator with more than three decades of experience, beginning her career in Pierce County in 1996 before being elected Auditor in 2013. She is a dedicated advocate for voter access, having championed legislative measures such as same-day voter registration, pre-registration for 16 and 17-year-olds, and automatic voter registration. 

A key achievement in Hall's career was her success in securing full state funding for elections, a critical financial burden that had been unfunded by the state for decades. She led the charge to persuade the state to begin picking up its share of election costs starting in 2022, a major victory for county auditors and a testament to her legislative advocacy. 

Her innovative leadership has also garnered national recognition. In 2020, she was named Auditor of the Year by the Office of Secretary of State and received a NACO Achievement Award for creating a drive-thru Voting Center during the COVID-19 pandemic, ensuring safe voter access during a presidential election.  In addition to her responsibilities in elections, Auditor Hall serves as the County’s Chief Financial Officer and oversees vehicle licensing, recording services, and passport processing.
