A family oriented city, nestled at the base of Mount Diablo in between Clayton, Walnut Creek, Pleasant Hill and Martinez. Concord is the largest city in Contra Costa County. Founded in 1869 as the community of Todos Santos by Salvio Pacheco, the name was changed to Concord thereafter. Featuring diverse landscapes, ease of transportation with BART and its very own airport! Concord is currently being revitalized with modern updates to its Todos Los Santos Plaza, the addition of world class shopping and dining at The Veranda and new developments to invite new family and business.
