Allen Lee was a Jesus Christ-centered man of faith who was a faithful, loving husband; a loving, respected, great father and grandfather; an innovative mechanical engineer solutionist; and an outdoor, animal-loving enthusiast. To our family and friends, he was our mentor, pillar, and man of integrity to emulate.
