Based on the belief that WE ALL HAVE SOMETHING TO GIVE, Casas por Cristo leads mission trips that meet the physical need of better housing in hopes of also meeting the spiritual need for Jesus Christ. It is through our partnerships with other organizations, local churches, and thousands of annual volunteers that we are able to address the needs of people living in poverty, one home at a time.
