Diana was relentless in her faith and love of Jesus. Life’s challenges only deepened her walk with Christ. She loved others well and had a wise and gentle spirit that soothed your soul. She had many loyal friends who loved her deeply.

Diana’s persistence and strength during difficulties inspired us all. In adversity, she chose joy! Her legacy will be her example of Christ’s love to all who knew her.

She married Alan Lee Littlefield on December 16, 1995, at Lawton Heights United Methodist Church in Lawton, Oklahoma.
