Mission Ace Lumber and Hardware has been serving Santa Rosa and the surrounding area since opening in 1999. Mission Ace is the second store location of O'Connor Lumber Company which has been owned and operated by the Pierre family in Vallejo for over 50 years. When deciding to open a second location the Pierres looked no further than their home town of Santa Rosa. Mission Ace is a full service lumber yard and hardware store, conveniently located in East Santa Rosa. We are here to meet the needs of the do-it-yourselfer and the professional contractor, with quality materials and courteous service.
