While in law school he became active in the peace and justice community and has been a member of the Louisville Human Relations Commission and Interfaith Paths to Peace. Peace Postcards has been nurtured by his interest in folk art and how it can relate to peace and understanding among neighbors and the larger world.

Peace Postcard exhibitions at the Honkawa Elementary School Peace Museum, Hiroshima, Japan, The Tehran Peace Museum, Iraq and The Mohammad Ali Center, Louisville, KY are examples of these efforts.
