It is further the intent of the Legislature that the voluntary services of persons from the professions of clergy, education, medicine, law enforcement, social services and such other professionally and occupationally qualified individuals as can make a contribution to this program be utilized in its implementation so that the highest possible degree of expertise may be brought to bear.
