Tim and Brooke

Tim Collier

Tim and Brooke met at a Boiler Room gathering in 2008 and got married in the Stockbridge Boiler Room's side yard 9 months later.  They share a passion for prayer, hospitality and seeing people walk in wholeness as children of God.  Their shepherding grace begins with their children Hazel, Gus, Walter and Maeve and extends to the entire Boiler Room family as they lead the community by opening their lives and home to share with friends and neighbors.

Tony and Jenn Tendero

Spiritual Dad/Mom

In 2006, the Tenderos heeded the call of the Wild Goose (Holy Spirit) to sell their dream home and move to the grungy and neglected neighborhood where their children's school was located. After a year of praying on their front porch and developing friendships with a few neighbors, they rented a second home to be used for prayer and to house interns who would serve the neighborhood. The rest, as they say, is history. They spent the next several years devoting themselves to interns, as a spiritual mother and father, and creatively engaging with the Holy Spirit to practice prayer, justice, and learning in the westside context and under the umbrella of 24-7 Prayer. In spring 2014, they stepped out of immediate oversight of the Boiler Room in order to follow the call of the God once more to Helena, Arkansas. They have since returned to Grand Rapids and live in Ada with their children.
