Cheryl Knox, 66,ย used to walk past theย Kempo Gojuย dojo on her way toย and fromย Keefe Avenue Elementary in theย mid-1970s.

She said she was enamored by the trophies in the window and the martial arts students training in the distance.

“I was captivated by everything,” Knox said. “I always thought, one day, I would go inside, and then finally I did.”

The students were practicing Kempo Goju, a martial arts discipline founded in Milwaukee by Charles Warren, 78, in the 1960s.

The karate style incorporatesย Chineseย Kempoย andย Japaneseย Gojuย Ryu and is an internationally recognized discipline, with dojos in Wisconsin,ย Mississippiย andย Europe.

Knox eventually joined Warren’s school when she reached the sixth grade.

Warren’s students were under a rigorous program, Knox said. Kempo Goju training required students to exercise daily to keep up with their classes.

He also taught about responsibility, and he led by example, she said, adding that he supported many students outside of class emotionally and financially.

Knox continued to train with Warren years after she left Milwaukee to attend the University of Wisconsin-Madison.

โ€œI canโ€™t overstate the impact he had on his students,โ€ Knox said.

How was Kempo Goju developed?

Warren developedย the integrated karate style in the mid-1960s after studying underย aย Kempoย master inย Albuquerque, Newย Mexico,ย and later, aย Gojuย Ryuย master in Japan.

He returned to Milwaukee in the late 1960s andย began toย blendย the rapidย and circularย hand techniques ofย Kempoย with theย traditional striking and blocking techniques ofย Gojuย Ryu in his own training.

By 1970, Warren began teaching his techniques to his first students, whom he met through his wife, Sharon Nash.

Warren and Nash started dating in their junior year of high school. When he left for service, they stayed in touch, but the distance at times was difficult.

When he returned to Milwaukee, they began again where they left off, and he asked her out on a date to the movies. When Warren went to pick her up at herย parents’ house, her brothers, Kevin, Reggie and Wayne, surrounded him.

โ€œThey told me, โ€˜If you areย gonnaย keep taking our sister out, weโ€™reย gonnaย we see if you can handle yourself,โ€โ€™ย Warren said.

Warren and the three brothers went down into theย basement,ย andย Wayneย was the firstย to stepย forward.

โ€œAnd boom! I punch him, and he is on the floor. Then the next oldest decidedย heโ€™sย tough and tried to box me, and I knocked him on the floor,โ€ he said. โ€œLittle Kevin ran upstairsย andย yells, โ€˜Mom!ย Wayneโ€™s on the floor in a ball!โ€โ€™

Warren said their motherย rushedย downstairs, looked around,ย and told the brothers to leaveย him alone.

Warrenย married Nash some years later, and they have been together for over 50 years.

In 1970, Wayne, Reggie and Kevin became Warren’s first students, and were known as The Milwaukee Kick Fighters.

The classes were small at first, comprising mostly Sharonโ€™s brothers and a few of their friends. The group trained at the old Northside YMCA on North 12th Street and West Garfield Avenue.

Eventually, Warren moved the budding school to a space near North Green Bay Avenue and West Silver Spring Drive.

By 1976, he moved The Milwaukee Kick Fighters to North 18th Street and West Atkinson Avenue.

Kempo-Goju gains traction

That same year, Warren andย eight ofย his students were invited to the U.S. Karate Associationโ€™s Grand Nationals Tournament in La Crosse.

They did not win the full tournament, but Warren’sย new Kempo-Gojuย style began to gain attention fromย the martial arts community.

โ€œWe did real,ย realย well,โ€ Warren said. โ€œPeople wanted to know where we wereย fromย and we said Milwaukee.โ€

Some organizers of the tournament saw the potential for Warrenโ€™sย school andย told him that the name of the school would not be taken seriously in nationalย tournaments.ย So, he changed the name toย Kempo-Goju, and Warren has been recognized as the discipline’s originalย master ever since.

As the discipline grew in popularity, Warrenโ€™s students began to take home trophies from tournaments across the countryย and internationally.

Over time, Warren began to incorporate other martial arts disciplines like Judo and Aikido to teach his students to be well-rounded enough to react to any situation.

What was expected of Kempo Goju students?

One of the key responsibilities Warren taught his pupils was how to show restraint, according to Knox.

If a studentย wasย put in a position where they had no choiceย butย to fight, they were expected to use methods that would do the least amount of damage, unless they were in a life-or-death situation.

โ€œIf one of us got into a fight, we wereย alsoย expected to come back and explain everything we did to avoid using our hands,โ€ Knox said.

It was called the “Circle of Honor,” according to Warren. If one of the students gaveย anย inadequate answer for why they chose to use force, they would have to complete an intensive workout or more difficult training to discourage the behavior, he said.

However, fights outside theย dojo or a tournament were rareย for Warrenโ€™s students.

According to Knox, other dojos had a reputation for students instigating fights outside class, but at Warrenโ€™s school, they maintainedย a reputation of excellence and honor.

โ€œYou couldย probably countย on one hand the number [of students] that got in trouble with the police,” Knox said.ย “He kept them on the right path.”

Because of his teaching style and the effectiveness ofย Kempo Goju, Warren’s students, including Knox, were contracted as security for local events.

The school provided security when Jesse Jackson visited Milwaukee inย the late 1970s.

โ€œI always said that if I got the chance to meet Jesse Jackson again, I would tell him, โ€˜Hey, did you know I did security for you back in the day?โ€โ€™ย Knox said.

Warren establishes a Kempo Goju dojo in Kosovo

Outside Kempo Goju, Warren served as a Wisconsin stateย trooper, and in 2000, his supervisors offered him an opportunity to travelย to Europeย to train police inย ล trpce,ย Kosovo.

Warren saw that the conflict in the region between the Federal Republic of Yugoslavia and the Kosovo Liberation Army left local children with little to do.ย  So, he began training children who were interested in martial arts in a nearby middle school gym.

The gym was damaged from bombings, and the school conserved electricity by shutting the power off at 7 p.m. every day.

โ€œAt one point, I was teaching over 50 kids,” he said.

โ€œThe kids would bringย candles,ย and we would train by candlelight.”

Some of his original students in the area took over the school and are still teachingย Kempo Goju in Kosovoย to this day.

Warren retired from the State Troopers in 2000 and remained in Kosovo for two years as a liaison.

When he returned to the U.S., he becameย the police chief of the Village of Palmyra in southeast Wisconsin. In 2012, he was dismissed over decisions he made that were deemed controversial.

Later, he became Palmyra’s municipal court judge and served for 10 years before retiring in 2022.

Where is Kempo-Goju now?

Today, there are four Wisconsin Kempo Goju dojos, including one in Brown Deer, Brookfield, Palmyra and Hudson.

There is also a dojo inย Mississippiย and Kosovo.

Training at Kempo Goju dojos typically begins around age 5, but all ages are accepted. According to the website, some students trainย wellย into their 70s and 80s.

Instructors are trained toย teachย students with injuries and mobility concerns.

Fees for classes cost about $45 per month, butย prospectiveย students are encouraged to call or inquire at specific locations.

Warren still helps instruct some of the classes, and he visits each location at least twice a year.

He wants his students to continue his legacy of not only exceptional martial arts but also showing respect and maintaining control over their emotions.

“The students here can go anywhere in the world, into any dojo, and be accepted because of what we have done here and the rules we follow,” Warren said.

“You gotta make good people, not just fighters.”
