Sr. Instructor

John J. Kastner

In the early 80's, I started training as a martial artist and fighting as a semi-pro fighter. I trained with some pretty well known top ranking fighters and martial artists. Men like Rick Rufus, Tommy Hall, Victor Johns, and Charles Warren here in Milwaukee, WI. After 38 years. I now hold a 5th. degree Black Belt in Tae Kwon Do, a 4th. degree Black Belt in Kempo goju Karate, a Brown belt in Judo, I also hold a purple belt in Jujitsu, and have studied MUAY THAI for ten years and hold the rank Kru instructor, I also have been involved American Boxing for 30 years and counting. 

At the age of 27 on Easter Sunday in 1993, (Please see the testimony link) Jesus saved my life and my soul, redeemed me from a lifestyle of sin, violence, and drugs. Thus began the greatest journey of my life, following Christ Jesus. 

From 2007 through 2009, my wife, Jami  and I started NDY (New Day Youth) to disciple the junior high and high school age students at New Day Church in Franklin, WI. Through Sunday service, Bible studies, worship services, social events, and retreats, Jami and I pointed the members of NDY in the direction of Christ.

Our unique style, called Christ Kune Do, is a blend of Biblical discipleship and full discipline martial arts utilizing the best of traditional styles combined with solid Bible based teaching. The physical techniques taught within Christ Kune Do is a well-balanced mixture of Kempo karate, Tae kwon do, American Boxing, Muay Thai, Jujitsu, Judo, and wresting. However, the primary goal of Christ Kune Do is to develop Disciples of Christ who are willing to speak the truth in love and stand up for those that cannot stand for themselves. The blending of styles, along with the desire to teach God’s word, is what makes this program one of the most well rounded Martial Arts programs available.

In 2011, I established Rising Sons Martial Arts to bring the love of Christ and my passion for honorable fighting to this community. Christ Kune Do is a new Bible based Christian martial arts made up of a combination many different fighting styles. The name Rising Sons eludes to the fact that students in this martial arts school are rising up in the Lord as well as their physical training. The bible states we are all sons of God.

Centered in southeastern Wisconsin in Milwaukee County, Rising Sons Martial Arts welcomes anyone interested in learning a Bible-based, Martial Arts called Christ Kune DoII Timothy 4:7 "I have fought the good fight, I have kept the faith”

Our mission through Christ Kune Do is to train and develop fully devoted followers of Christ Jesus. We accomplish this through daily bible study , group study, bible memorization and physical training. We train our students to truly become Fighters for Christ Jesus in everyday living, to further the kingdom of God.





 The bible reads in Jeremiah the 29th. chapter 11 through 13 

11 For I know the plans I have for you,” declares the LORD, “plans to prosper you and not to harm you, plans to give you hope and a future. 
12 Then you will call on me and come and pray to me, and I will listen to you. 
13 You will seek me and find me when you seek me with all your heart. 

I know my God has a plan for this ministry. We here at Rising Sons seek always God will for our martial arts as well as our daily lifes. Please join us in our quest to bring the word of God to everyone we meet.
