In 1988, Riverside Mandarin Baptist Church began with family studies and worship. Thanks to the concerted efforts of faithful leaders, brothers and sisters, and after much prayer and searching, Pastor Chang Chi-Chong was called to help them establish the church. The church moved to a location at California Baptist University on April 29, 1990, and established Riverside Mandarin Baptist Church.

In 1992, God showed us abundant grace and sent Pastor John Lee and his wife to shepherd the church. In 1994, RMBC began renting from Indian Hills Baptist church for worship service. Then, with the help of Pastor Mike Wolf, RMBC purchased half ownership of the church. During this time, RMBC went through many trials, but God guided us with His pillar of cloud and pillar of fire, and we dared not to stray from Him and His plan for us.

In 2002, by the grace of God and with the great help of Pastor Paul Wilkerson, Riverside Mandarin Baptist Church and Tyler Baptist Church merged. God brought us from the wilderness to the Promised Land he had prepared for us. He called Pastor Bill and his wife to come shepherd us, and brought Pastor Wolf and his wife to help minister to the church. God then provided Pastor Gershom Lee from 2007 to 2012 as Chinese pastor to care for and lead the spiritual growth of Chinese brothers and sisters.

In 2013, God sent his servant, Pastor David Chao, as well as his wife, to RMBC. In 2015, Pastor Adam Co and his family joined to nurture the English congregation. In February, 2018, Pastor Terry was called as English pastor.

Beginning on July 1,2022, Pastor Charles Sun was called as Chinese Pastor to shepherd RMBC.

In the Lord we are one, we love one another, live in harmony, work tirelessly according to God’s will, and wait for the day of the return of the Lord.
