Jim was a cheerful servant to his church and his community. At St. Barnabas, he was an elder and taught adult and children's Sunday school. He was the Democratic precinct chairman in Cottonwood Creek and helped serve meals at The Bridge, a Dallas homeless shelter. Jim's mind was unconstrained by convention. He was insatiably curious, full of joy and whimsy. He was a loving husband, father, grandfather, brother, uncle and friend. God granted Jim serenity, courage and wisdom.
