After Calvary, he spent almost 10 years in youth services in Illinois and Colorado including five years as a Camp Fire USA Council Executive Director in both Illinois and Colorado. In addition to working with the homeless and youth, Joe has led organizations that work with disabled adults, the poor and working poor and feral and stray cats (getting them spayed or neutered).
