Landmark Church

About this church

Landmark Church gathers in Diamond Bar on Sundays at 8:00, 9:30, and 11:00 a.m., with online participation available. Its location near the meeting point of Los Angeles, San Bernardino, and Orange counties shapes a mission to serve a culturally diverse region as well as partners in Asia and Africa. Visitors who complete the Plan My Visit form at least two days ahead receive a confirmation naming a host, explaining where to meet, and outlining what to expect on arrival.

Landmark Kids serves birth through fifth grade, while Landmark Youth connects junior-high and high-school students through worship, prayer, Scripture, and conversation. Young adults meet Tuesdays at 6:30 p.m.; a midweek message follows Wednesday at 6:30, and a traditional service is held at 11:00 a.m. on the first Wednesday of each month. Life Groups and community-outreach classes offer smaller settings beyond weekend worship. Three Sunday choices and the optional personal host make this large, active congregation easier for a newcomer to navigate.
