Leadership and Staff


Milton Vincent

PASTOR-TEACHER | elder | staff


Milton Vincent has served as Pastor-Teacher of Cornerstone Fellowship Bible Church since 1992. He is the author of “A Gospel Primer for Christians: Learning to See the Glories of God’s Love” published in 2008. This book stemmed from his daily struggles into a greater understanding of his justified status before God. What started as a few notes on index cards moved to a spiral bound booklet that was eventually published into book form. 
Milton and his wife, Donna, were married in 1987 and have four grown children. He has had the unique privilege of walking both of his daughters down the aisle and officiating at their weddings. He is a graduate of Bob Jones University (BA) and The Master’s Seminary (MDiv) and has served as a Faculty Associate at The Master’s Seminary in Sun Valley, California. 
Most of all, Milton sees himself as sinner saved by the grace of God through Christ, and he delights to speak of God’s amazing grace to all who care to listen.

Mario Limon



Mario and his wife Kellie first attended Cornerstone on Father's Day in 2010, hopped in the car after church, and asked each other, "Is this real, or a dream?" and have been pinching themselves ever since. The gospel-centered sermons put the wind in their sails, and they walk out encouraged week after week.
Mario and Kellie have been married since 1989 and have three beautiful children. Two of them, Samuel and Hannah, now attend California Baptist University where Mario is employed. Their youngest, Micah, is in high school. The Limons finally moved to Riverside after living in Murrieta for 24 years.
Mario oversees Inreach Ministries, including Connections, Agape, In-House Catering, and the Safety Team. His spiritual gift is mercy, and he is passionate about discipling his children to follow Jesus Christ more closely. You will typically find Mario at 2nd Day Man Forum on Tuesday mornings at 6:00 am, with a cup of coffee in hand, and wearing a LA Dodgers cap.
