Adrenaline Martial Arts Academy means 'family' business
Bob, the oldest of the Mueller brothers, was the first one to get involved with martial arts, while the family still lived in Eagan, Minn. That was in 1989. Jeff and Joel each started taking karate when they were 12 and nine respectively. The family had moved to Baldwin by that time.
"It was something that kept them straight and taught them responsibility," said Bob, of his brothers.
"When you are a kid in this environment there is always an adult with you," said Jeff.
