Hanford Sand and Gravel, Inc. started out with Preston [Sr] and Iris Hanford having a dream of starting a business that would ... grow and prosper with the surrounding communities throughout the Sacramento Valley.

Both companies did great and in 2005 Preston [III] Hanford took over operations of Hanford Sand and Gravel, Inc. and added a Ready Mix division in Roseville, CA. selling ready-mixed concrete and other related items. read more
