The Olivia Caldwell Foundation is hosting its ninth annual Butterfly Ball on Saturday, offering the community an opportunity to dress up, dance and support life-saving pediatric cancer research and programs that serve children battling pediatric cancer and other diseases throughout Wyoming and surrounding areas. “This is our ninth year of the Butterfly Ball and it’s a fundraiser that we started in memory of my daughter, Olivia,” said Olivia Caldwell Foundation CEO and founder Katie Burchett. The number of people who know and go to the Butterfly Ball year after year create a reception that never ceases to amaze Burchett. The Butterfly Ball is happening Saturday, Jan. 31, beginning at 7 p.m. at the Ford Wyoming Center. “I would just say, make the most of the Butterfly Ball,” Burchett said.
