The Town Clerk serves the people of Hillsdale by acting as a bridge between each citizen and the Town government. Because access to information is essential in a democracy, the Town Clerk maintains and makes available the records of the Town. Because certain licenses and permits are required by State and local agencies, the Town Clerk assists in filing applications and issuing licenses.

Kathi Doolan is Hillsdale's elected Town Clerk and will serve until December 31, 2023. She also serves as Registrar of Vital Statistics, Records Management Officer, and Information Access Officer.

Deputy Town Clerk, Elizabeth Sheer, was appointed to her position in September 2020.
