George McDonald and Harriet Karr-McDonald are the founders of the Doe Fund, a non-profit organization that trains and houses homeless men in New York City and Philadelphia who are "Ready, Willing and Able" to work. The men are ex-drug addicts, ex-offenders and military veterans transitioning back into society. The organization was named in honor of a homeless woman known as "Mama Doe" who died of exposure on Christmas Morning 1985 in Grand Central Terminal.
