The Holy trinity Church of McLean is a modern church which welcomes people from all backgrounds and beliefs so that they can have a healthy and meaningful discussion on God and life. It believes that a church should serve the community as a whole and not just its members. It offers three courses - the Alpha course, the Marriage course and the Parenting course which are non traditional and unconventional but still based in Christian principles. There are children and youth ministries available for younger members where they can explore Christianity and faith through activities and lively discussions. There are free guitar lessons also offered by the supervisor. The church also encourages its members to participate in volunteering projects as community service is considered to help people in growing close to God.
