History
Thornton consisted solely of farmland until 1953, when Sam Hoffman purchased a lot off Washington Street about 7 mi north of Denver. The town he laid out was the first fully planned community in Adams County, and the first to offer full municipal services from a single tax levy, including recreation services and free trash pickup. Thornton was named in honor of then-incumbent Colorado Governor Dan Thornton.
