Cornerstone Fellowship is a non-denominational Christianmegachurch in with headquarters in Livermore, California. The Lead Pastor is Steve Madsen. Cornerstone Fellowship was founded in 1992 and it currently has five campuses, one in Livermore, one in Brentwood, one in Hayward, one in Walnut Creek, and one in Danvile California. Every week, over 5,000 people come to its eight weekend services.
In 1992, Steve Madsen resigned from a church in Dublin, California, and started a Bible Study in his own home. The first study was on the book of Galatians. At the end of the first year of Bible Study, the group organized itself into a church. Cornerstone met in a rented hall, going from one, to two, to eventually three services until there was no more possibility of expansion. Providentially, at that time a former indoor soccer facility that had previously been refused was offered at half the previous price. In 2004, the church purchased this building and converted it into a 24,000 sq.ft. facility. Although the 1800-seat auditorium is currently the largest venue in the Tri-Valley, Cornerstone's dedication to serving the next generation is evidenced by the fact that two-thirds of the flagship building is for children's ministries. Services at the main campus are held Saturday evenings and twice on Sunday, and at various locations in Hayward, Brentwood, and Walnut Creek. Cornerstone emphasizes the importance of meeting together in smaller groups throughout the week for support, fellowship, and accountability.
