After serving in the Navy for 10 years and working in corporate America building data centers, Dan Umpa has launched USA Ninja Challenge Stafford, an indoor obstacle course training program that combines basic skill sets from gymnastics, climbing, cross training, and track and field.
Umpa, who graduated from the Naval Academy, originally planned to open a gym. He had spent ten years working in the corporate world, building data centers, and knew this type of career didn’t fit his needs for more time with his family or his active lifestyle.
