Hoover-Minthorn House Museum

Black and White portrait of past president Herbert Hoover

The only presidential house museum in the Pacific Northwest, the Hoover-Minthorn House Museum strives to preserve and interpret the childhood home of the 31st U.S. President Herbert Hoover, who served from 1929 to 1933, and his Minthorn family who took him in as an orphan.

The Hoover-Minthorn House Museum’s collection boasts original artifacts owned by the Hoover-Minthorn family and other 1880s items that represent Newberg at the end of the nineteenth century.
