MLC Board Members

Stephanie Hobby
Board Member
Stephanie is a science writer and a mom to two enthusiastic MLC campers. She believes that childhood is the optimal time to encourage a fascination with the wonders of the natural world.
“Children are naturally curious, and asking questions is basically what’s at the heart of science. One of the things I love about the MLC is that it fosters that curiosity in a non-threatening, engaging environment where learning – not grades or a test – is the goal. They’re just having fun while playing with some pretty high-level concepts.”
Stephanie grew up in Oregon and Virginia, and attended the University of Missouri before moving to Billings in 2001 to work as a television reporter. While she loved the daily variety and new experiences that journalism offers, she returned to school to focus on communicating complex scientific topics.
She earned her master’s degree in technical communication at the University of Washington, and worked for the renowned Fred Hutchinson Cancer Research Center and later the UNM Cancer Center in Albuquerque before landing a dream job at Sandia National Laboratories, dubbed by Wired magazine as “The Playground of Big Science.” When the opportunity arose, they jumped at the chance to return to her husband’s hometown of Billings.
In addition to her work as a writer for the MLC, Stephanie is honored to write for Stanford University Medical Center, raising funds for vital medical research, and local magazine, Simply Local Billings, highlighting incredible people and projects from her community. She enjoys volunteering with her children’s schools, church, and their family’s ski team.
