In 1930, a group of families seeking strong Bible teaching formed what was then known as the Independent Brethren Church of Glendora.  Men from IBCG mined rock quarries in the mountains above the citrus farms of Glendora and brought down large stones out of which they built our main building.  In August of 1931, the new church celebrated its first formal meeting in the new building.

In the late 1980s, the church membership approved a change of name to Cornerstone Bible Church. Today the church continues to experience God’s blessing with growth and expanded ministries under the leadership of Pastor Bruce French and a dedicated staff of men and women who are committed to the faithful teaching of God’s Word and to our vision of Loving God & Others Well.
