Mentors provide a critical consistent nurturing relationship for a child.
Unfortunately, because most of a child's support team are paid professionals, the support team often changes, causing even more transition for a child.
Mentors can provide a long-term, foundational, nurturing relationship. They can be a constant factor in a child's life helping the child to heal.
There are many great programs for mentoring foster youth.
