Adrian Garcia

Associate Pastor of Student Ministries and Missions

Adrian Garcia grew up in a family of nine kids in Torrance, California. His oldest brother became a Christian and shared the gospel with him at an early age. At the age of twenty-one, Adrian realized he was a sinner at enmity with God. He cried out for mercy and placed his faith in Jesus Christ as Lord and Savior.

Shortly after becoming a Christian, Adrian was given a hunger and desire to know God’s Word. This resulted in reading, studying, and utilizing sound resources to understand the Scriptures as much as possible. At the same time, there was an eagerness to serve wherever needed within the local church. In God’s providence, Adrian was directed to Student Ministries and has served both as a small group leader and Pastor for a combined twelve years.

By God’s grace, his aspiration to comprehend more of God’s Word led to an opportunity to study at The Master’s Seminary, where he is currently a student.

Adrian and Ashley have been married since 2011 and have three boys: Ezra, Eli, and Ezekiel. Adrian enjoys reading, exercising, and spending time with his family.

Adrian’s favorite verse is Psalm 121:5, “The Lord is your Keeper, He is your shade on your right hand.”

Jesse Howard

Associate Pastor of Music & Discipleship

Jesse was born in Colorado Springs, Colorado, into a loving Christian home. His parents faithfully presented Christ to him, and at an early age he accepted Christ as his Lord and Savior. God provided amazing men to disciple Jesse over the years allowing him to grow in his knowledge and love of the Lord. Jesse grew up an avid tennis player, but at the age of 16 started experiencing chronic back pain that has remained with him since that time. God used this trial to draw Jesse into a deeper relationship with Himself as well as put him on a path in the music industry. It was also at this time that he met his future wife, Ali. Ali and Jesse enjoyed seven years of friendship and dating before getting married in 2011.

Jesse moved to Nashville in 2010 to pursue his music career. While in Nashville, God blessed Jesse with wonderful opportunities to perform and record with many different artists. After 5 years, Ali and Jesse felt the Lord calling them to seminary. They moved to Los Angeles to attend The Master’s Seminary. After four-and-a-half years of school and working at TMS, Jesse and Ali connected with Cornerstone. With his background in music and his love for discipleship, Jesse joyfully joined the pastoral staff in August of 2019, as the Associate Pastor of Music and Discipleship.

Ali and Jesse have one daughter. He loves spending time with his family, gardening, being outside, playing guitar, studying God’s Word, and reading.

Jesse’s favorite verse is Romans 5:3-5. “And not only this, but we also exult in our tribulations, knowing that tribulation brings about perseverance; and perseverance, proven character; and proven character, hope; and hope does not disappoint, because the love of God has been poured out within our hearts through the Holy Spirit who was given to us.”
