Mailing Packages and Letters to San Luis

Want to send a package to the Oasis Boys, supplies to the church, or an item to any of our other ministries?  We have a PO box in San Luis Arizona so that you can mail packages, and someone crosses to check this box every 1-2 weeks, or when we know something is on the way. Before purchasing your item, contact Natalie at missions@caringheartsmexico.org to make sure the item is approved for one of the Oasis boys etc. Next, fill out the form below when you mail so we know to pick it up!
