Our school was opened by Renshi Bob Duemig in 2014.  He began his training in JuJitsu in 1987 while stationed at Ellsworth Air Force Base.  He worked hard to earn his black belt at the adult sessions as well as assisting his instructors 'Mutch' Usera, Rod Holmes and Rich Wells with youth classes.   He attained his 1st Degree Black Belt in 1990.  After a serious car accident  and an Air Force reassignment, he had to take a break from the martial arts.

After becoming a pastor, he was encouraged by his church to teach a self defense class to the youth which developed into a new school.  Shortly after moving to Belle Fourche, he opened Northern Hills Bujin Ki Ryu JuJitsu.  Renshi Bob attained his 4th degree Black Belt in October 2017.


He retired in 2019.
