Bay Area native Joel A. Harris has lived in Concord and Clayton for 20 years and is a local trusts and estates attorney. His wife, Christy, attended Concord High School and owns Clayton Books. The amazing photographs included in this book come mostly from the collection and efforts of the Concord Historical Society. Concord photographer Leah Pels prepared all of the images, which detail the growth of Concord from a vast wilderness into a farming and ranching town and finally into the commercial center it continues to be today.
