Meet John Leiber
John Leiber was elected Wisconsin State Treasurer in November 2022 and took office in January 2023. He didn’t come to Madison to invent a new job. He came to do this one.
​
His hometown is Caledonia, where his family roots run four generations deep. He has spent his entire adult life in Wisconsin — as a legislative staffer in the Assembly and Senate, a tax advisor at the Department of Revenue, and an attorney in real estate, wills and probate. In Racine County he led as president of his local Park and Recreation Commission and served as a Housing Authority commissioner.
Grassroots work is not a recent hobby. John volunteered on his first campaign more than 25 years ago and has fought to elect conservatives ever since—as a campaign manager and a board member of his local Republican Party.
​
He earned a BA in History from UW-Parkside and a law degree from the University of Wisconsin Law School. John and his wife, Diane, live in Cottage Grove. They have three adult children.
Since taking office in January 2023, Treasurer John Leiber has done the job Wisconsin elected him to do: protect taxpayers, keep the office lean, and grow the school trust that buys books and technology for every public school district in the state.
​
Grew the school fund that belongs to Wisconsin kids
Leiber serves on the Board of Commissioners of Public Lands, the constitutional board that manages the state’s school trust funds. The Common School Fund is the only dedicated statewide source of aid for public school libraries and school technology.
​
On his watch:
-
The Common School Fund has grown to about $1.6 billion.
-
Annual library aid has set new records three years running: $65 million, then $70 million, then a record $73.5 million for 2025–26.
-
Those dollars go to every school district in Wisconsin for books, literacy materials, and classroom technology — and they take pressure off local property taxes and grow the school trust that buys books and technology for every public school district in the state.​

Results. That is the record.

Kept the office lean
The Office of the State Treasurer is staffed by one employee: the Treasurer. Leiber has not built a bureaucracy or invented new programs. He has administered the constitutional duties of the office, advocated for fiscal restraint with the Legislature, and focused on the assets he is charged to oversee.
​
Returned focus to the job, not the next job
Leiber ran on a simple promise: do this work, do it well, and do not use the Treasurer’s office as a stepping stone. He has kept that promise. He is an attorney with experience in tax work at the Department of Revenue, legislative staff service, and local boards. He treats the school trust like a trust — principal protected, income maximized, benefits delivered to the public.
​
Promoted money that belongs to Wisconsinites
The Treasurer’s office promotes Wisconsin’s unclaimed property program so forgotten accounts, refunds, and assets get back to their owners. The state still holds hundreds of millions of dollars that belong to residents. Leiber’s position is straightforward: that money is not Madison’s to sit on. It should go home.
​
Results. That is the record.
