    Shihan Chris supervises all daily operations of the dojo as well as all instructors and assistant instructors. 


    Shihan and staff also teach at various local nursery schools, daycare facilities, summer camps and recreation departments.

    Ryu Renshi-Dan Karate has built an incredible reputation over the last 47 years. 


    Ryu Renshi-Dan, meaning "The Way of the Honorable People" was founded in 1977 by Hanshi Jose Guzman, 9th degree Black Belt. 


    Ryu Renshi-Dan is an eclectic blend of 3 traditional Japanese arts: Shotokan, Goju and Isshinryu. 


    Hanshi Guzman was the Chief Instructor from 1977 - 2009. During his tenure he produced many National champions in both forms and fighting. Hanshi and his students spent many weekends traveling the Country and putting RRD on the map as a fierce contender. 


    In 2009, Hanshi passed over the reigns of the Dojo to his son, Chris. Shihan Chris has been involved in the martial arts his whole life. 


    Shihan really took the dojo to the next level and expanded programming to run 6 days a week. Shihan Chris has now developed some amazing Black Belts of his own that you can find helping out with classes and teaching weekly.
