Hello, I'm Master Bill Koster, 6th degree Master, Owner/Operate of Karate America Mixed Training Systems in Sun Prairie as well as Marshall and a Corporate Program at Covance

Karate America Mixed Training Systems had may events and activities that we participate in year round.  I invite you to experience some of the activities such as Corn Festival, Church Festivals, and workshop/seminars to name a few.

While this page is still under contruction, I invite you to look at our 2009 Events and 2010 page.  Our front page of photos will soon have "in house" photos of classes in session, stripes issued for cooperative skills advancement, and belt awards.  We will try our best to have photos of each belt awarded and welcome you to share your photos with us as well.  Please send jpgs to Ms. Stevens.

Thank you to THE BEST students and families in the area.  It is a pleasure to serve such hard working and dedicated students on a daily basis.  I continue to actively train so I can bring you the most cutting edge techniques in the Mixed Martial Arts world.
