Since 1952, the Open Plymouth Brethren assembly now known as Mission Valley Community Chapel has operated from 6964 Mission Gorge Road in Grantville, San Diego, running an all-volunteer leadership model that directs roughly 80 percent of congregational giving toward worldwide missions. Elders Clint Cable, Jim McDonald, Scott Raymo, and Tom Cantor oversee the 92120 campus, with deacon Ken Willadsen handling operational logistics. The missions-focused budget model funds field workers and partner organizations across multiple countries, aligning with the retreat and outdoor-ministry programming at Whispering Winds San Diego Office in Grantville. The weekly schedule begins with the Lord's Supper at 9:30 on Sunday mornings, followed by all-ages Sunday school, a patio coffee break, and an 11:15 worship service that anchors the congregation's multigenerational format. A midweek prayer meeting runs on Wednesday evenings. The chapel's Mission Gorge Road address places it on the commercial corridor that connects Mission San Diego de Alcala to the south entrance of Mission Trails Regional Park, a stretch that generates foot and vehicle traffic from hikers and tourists year-round. The property hosts the Iranian Christian Church of San Diego under a co-tenancy arrangement that partitions Sunday scheduling between the two congregations. The Open Brethren tradition means the chapel operates without a salaried pastorate, with elder-led teaching rotations replacing the single-pastor sermon model common in most evangelical assemblies.
