Sophia Ma - Associate Pastor of Community Connection

Born and raised in New York City, Sophia moved to the Boston area for school (Wellesley College '98 and Tufts Occupational Therapy program '02), and has now called Antioch Community Church of Waltham home since 2014.  Sophia is passionate about people experiencing God's transforming love in community and longs to see people own their identity as God's beloved children. As someone who has personally experienced deep levels of healing and freedom in her walk with Jesus, Sophia is eager to see this same freedom for others who may walk in shame or bondage.  Sophia's role on staff is to help build intentional community by supporting community group leaders as well as helping individuals get connected and build relationships.  

In her free time, Sophia enjoys taking walks/hikes with her husband and two children, playing her ukulele, and connecting with her family and friends. She also loves playing anything that creates laughter and bonding... and may even bring out some fun competition! Sophia's favorite friendly competitions range from fish bowl and charades to ultimate frisbee and volleyball.

Richard Wang - Administrative Coordinator

Richard grew up in China and moved to the US for college at the University of Wisconsin-Madison.  It was his mother's boldly sharing the Gospel and persistent prayer (though new in her own faith), as well as Cru's fellowship that led Richard to give his life to Christ right before finishing his masters degree in statistics.

Since moving to Boston for his current job as a data scientist in a marketing research company, Antioch Waltham has been the nurturing place for Richard's faith and growth in following Jesus.  Richard also met his wife Amanda at Antioch and they now live in Waltham.  Richard is passionate about helping others know and follow Christ through discipleship, especially as he understands what it was like to walk apart from Jesus.

Christopher Greco - Worship Pastor

Christopher has been leading worship for over 30 years in the Boston area. He and his wife Dorothy feel most at home in multi-generational, multi-ethnic and Spirit-attuned settings. Weekdays, Christopher directs theatre at Lexington Christian Academy and manages their worship and performing arts center.

He describes himself as “equal parts contemplative, fiery Italian, neurotic stand-up improviser, and empathetic pastoral care-giver.” His training is similarly eclectic: film and TV at Boston University (B.S. 1985), playwriting at Brandeis (M.F.A.1992), and counseling and theology at Gordon-Conwell Theological Seminary (M.A. 2017).

Christopher and Dorothy love to kayak, hike, host, and collaborate with God in seeing the impossible come forth in the lives of men and women.

Tim & Sarah Yoon - Directors of Young Adult Ministry

Tim and Sarah are passionate about Young Adult ministry as they both became Christians as young adults. Their lives were transformed by the love of God when they encountered the Holy Spirit in powerful and intimate ways. This experience significantly changed how they perceive God’s heart and kingdom, as well as our identity in Christ.  They want everyone to know that He is alive, His love is real, and He desires to talk/interact with every one of us today as in the early days of the gospels.  The Young Adults groups strives to foster the sense of community by loving God, each other, and the world around us.

Tim is currently working at a tech company. He has a B.S. from Cornell and a Ph.D. from M.I.T.  He was on a M. Div track at Gordon Conwell Theological Seminary (hoping to continue and finish it some day!). Sarah is working as a dentist. She has a B.A. from Vanderbilt and a D.M.D. from Boston University. Tim and Sarah love reading, hiking, biking, and taking day trips with their three children.
