Master Koster is the owner and senior chief instructor at Karate America Sun Prairie.  He received his first black belt in Tae Kwon Do in 1981 from nationally respected Dr. Sang Kee Paik.  Mr. Koster taught and trained under Dr. Paik.  Eventually he became the first director and instructor for the children’s program at Karate America – West Madison along with Mr. Randy Reid. 

Mr. Koster currently trains under the direction of Grandmaster Ron Van Browning at Trainers Elite.  He trains in Modern Arnis, Jiu-Jitsu, and Muay Thai to name a few. 

In June 2008 Mr. Koster was awarded his 6^th degree black belt.  The 6^th degree warrants the title of “Master” of the art. 

Master Koster runs programs in Marshall and Poynette as well as his home school in Sun Prairie. He has been running schools in Dane County for 25 years.

He trains at the highest level and the excellent training students receive have enabled some to become independent owners of other martial arts facilities.  This is a great testament to the quality of training you receive – to excel you must learn from, and train with, the best.

Master Koster "trains the trainers" so why settle for less? 

When checking out schools, find out if daily classes are led by a Master. 

This is important in your selection of a school.
