Jilian loves to travel, specifically to locations where she can get outside to explore nature. Before having children, in a four-year period, she traveled to Uganda, Kenya, Peru, Costa Rica, Puerto Rico, Milan, Cyprus, Hawaii, and many national parks throughout Utah, Colorado, and Wyoming. Now, two kids later, she and her husband are teaching them to be active and explore new things – but, for now, they’re doing it a little closer to home.
