Meet Our Leadership

  • Jojo Ma

    Lead Pastor - Elder

    Jojo was born in 1973 at a U.S. Military Hospital in Bangkok, Thailand.  His family moved all over the world until finally settling down in Arcadia, California in 1982.  Jojo graduated from the University of California Irvine in 1995, then completed his seminary studies in 2000 at the Talbot School of Theology (Biola University).  He spent 11 years as a pastor at Evergreen SGV before being called to shepherd CrossLife Community Church, a church plant of FCBC Walnut, in May of 2010.  Jojo is an ordained minister in the Southern Baptist Convention.
    Jojo is married to his best friend and the love of his life Terry (with the unanimous view that he married "up"); they have 3 children (and regularly foster children).  Jojo’s all-time favorite movie is “The Princess Bride” (it is “inconceivable” that a better movie exists).  He enjoys reading, listening to Sovereign Grace music, Andrew Peterson, Norah Jones, and Jack Johnson, playing sports of all sorts, adding Sriracha hot sauce and crushed red peppers to almost everything, cheering on the Washington Redskins, Anaheim Ducks, and the Lakers, but most of all spending time with his family.

  • Justin Chan

    Associate Pastor - Elder

    Justin was born in Pasadena, California in 1986. He grew up in Diamond Bar and attended First Chinese Baptist Church of Walnut from a very young age. At Walnut he first heard the gospel and trusted in Jesus as his Lord and Savior.  Justin graduated college in 2008 at the University of California San Diego and finished his pastoral education in 2012 at the Master's Seminary.  After seminary, Justin began attending CrossLife Community Church. He has been pastoring CrossLife since 2014.

    Justin considers himself blessed to be a part of the CrossLife family.  He loves being a member who serves, learns, and grows with God's people. His passion in ministry is to see people transformed by Jesus’ amazing gospel. Justin enjoys drinking coffee and green juice, buying anything from Trader Joe's, listening to Emily King, Funk/Jazz, and good ole 90's music, jumping on the Golden State Warriors' bandwagon, reading the Puritans, and simply being with good company.


  • James Mark


    James was born in Hong Kong.  His family immigrated before he was a year old, and he's lived in California ever since.  After graduating from UCLA (go Bruins!), he spent a year teaching English in Taiwan (he wanted to learn Mandarin, but that's another story).  It was there he discovered his love of teaching and has been teaching elementary school in Los Angeles for over 30 years.  He has been serving the Lord at CrossLife Community Church since its inception.

    James is married to his lovely wife Paula and has 4 sons (what was he thinking?!), ranging from middle school age to young adult.  He enjoys spending time with his family and traveling.  Over the last few years, James has learned the joy of eating (he used to be paper thin) things other than a medium rare steak.  He also enjoys sports, epic movies like "Lord of the Rings", "Star Wars", "Star Trek", and reading good books.


  • Ronald Yuan


    Ronald has lived in Southern California practically all his life.  The Lord has blessed him with a beautiful wife Grace, and 2 wonderful children Valerie and Nathaniel. Ronald graduated from USC with a PharmD and has been practicing pharmacy for over 30 years.  His leisure time at home consists of tickling the ivory keys and tilling the ground in his backyard by the sweat of his brow. Ronald also enjoys the great outdoors (he’s an Eagle Scout!) and focuses his vacations on hiking and sightseeing around different venues around the world.

    In terms of ministry, teaching children in Sunday School, and seeing God’s Word transform hearts, has always been a long term passion and joy.  Serving and leading in song-worship is another delight of his heart.  One of his favorite hymns is “Make me a Blessing”, which is his desire and prayer as a deacon to those at CrossLife.  Since coming to CrossLife, his theme verse has become 1 Corinthians 10:31: “So, whether you eat or drink, or whatever you do, do all to the glory of God.”


  • Joyce Young

    Children's Director

    Joyce was born and raised in Southern California and grew up at First Chinese Baptist Church of Fountain Valley.  She never thought she'd be a Sunday school teacher.  Over the last few years, God has shown her differently AND increased in her heart a desire for kids to really know Him and love Him beyond Sundays.

    She is happy to serve and support the Sunday school teachers, and desires for our kids to know Christ.
