From Humble Beginnings

In 1946, we started this family owned business with the idea of making home ownership a reality in Gridley & the surrounding communities. With our founder Everett Hamman running the show we became well known in the real estate industry for helping the hard working families fulfill their dream of real home ownership or counseling them on creative real estate transactions.
