A devout follower of Jesus, Shirley’s faith was central to her life. She was an active member of Hill Country Fellowship, where she found deep community and purpose. Shirley was also deeply engaged in the Highland Lakes community, serving as Vice President of the Highland Lakes Senior Center and as a long-standing member of the Legends Social Committee.
