Bill is the pastor of Cornerstone Ministries of Napa Valley.
He was born in San Francisco in 1955, but moved to Orange County in 1961. He attended Fullerton Junior College, and then Cal State Fullerton, graduating with a Bachelor’s Degree in Liberal Arts/Music.
His first ministry involvement came in 1980, with the Christian band “Undercover,” which was part of a music movement in Southern California. He sang on Undercover's first three records. Playing to youth as a traveling music-missionary, he felt a calling upon his life to be involved in serving Jesus Christ.
He started teaching the Bible in 1984 and soon realized that teaching/pastoring was the first priority for his life. He also sang with two other Christian rock groups: “The Fourth Watch” from 1984-1988, and then with “The Mirrors” from 1988-1992, recording one album with each group.
In 1989, he went on staff at Calvary Chapel Costa Mesa, under the leadership of Pastor Chuck Smith. He served there for two-and-a-half years as the College and Career Pastor, being ordained in 1990. In 1991, he was asked to consider starting a new church in Napa, and his young family moved there in September of 1991.
Bill and his wife Debbie, who have been married since 1982, have three adult children: Sarah Schrader, who is married to Caleb; Chris, who is married to Melissa; and Jonathan Walden. Bill and Debbie are blessed with four grandchildren.
