The Global Mission Church is located on Sunset Crossing Rd., right off of the 57 freeway. It is a Presbyterian church which offers both Korean and English language services to the Diamond Bar area. Of particular interest to the church are the young adults of the community. To that end, GMC, as it is known, provides various outreach programs to young adults and also to twenty-something singles. On Friday nights, it offers college bible study groups and social mixers and once a month it offers a newcomer BBQ to welcome post college individuals to the congregation. Various discipleship trainings are also offered throughout the year.
