He married his high school sweetheart, Tulia, and moved to Boston for seminary (MDiv, Boston University School of Theology, 2017).

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.
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 is working as an executive vice president at a tech company. He has a B.S. from Cornell and a Ph.D. from M.I.T. He also attended Gordon Conwell Theological Seminary and Bethel Seminary on a M.
