  • Tami Sabey - Administrative Assistant

    I volunteered for 2 years as a Patient Greeter and was continually touched by the families that are helped physically through medicine and spiritually through the staff's love and prayers. The pastors that volunteer to lead a daily devotion time for the staff also made a big impact. I wanted to be a part of this special group of people that really show what it looks like to the the hands and feet of Jesus. In God's timing, the clinic moved to a larger building and there was a need for a Volunteer Coordinator. I was and still am thrilled to be a part of what God is doing in our corner of Houston.
