Worried about your child’s confidence, focus, or screen time?
You’re not alone. Today’s parents are watching their kids struggle with distraction, low self-esteem, and fewer chances to build real-world skills. You want something different for your child — something that builds character that lasts a lifetime.
Distracted or unfocused
Trouble paying attention at school or finishing what they start.
Too much screen time
Less movement, fewer in-person friendships, more anxiety.
Worried about bullying
Online or in person, kids need tools to stand tall and respond well.
Lacking confidence
Shy, hesitant, or unsure of themselves in social situations.
Brookfield’s most trusted martial arts school since 1988.
Founded by 9th-Degree Grandmaster J.K. Lee — a name Wisconsin families have trusted for nearly four decades.
We don’t train fighters. We train better humans. From our Brookfield headquarters, we’ve helped thousands of kids, teens, and adults grow stronger physically, mentally, and emotionally.
What your child gains in their first 30 days.
Real changes parents notice — at home, at school, and in life. Sharper focus. More confidence. A calmer, more grounded version of the kid you already love.
Sharper focus
Kids learn to listen, follow through, and stay present — skills that pay off in the classroom and at home.
Greater self-discipline
Through structured progress and belt achievements, students learn the value of effort and consistency.
Real confidence
Not the fake kind. Earned confidence that comes from setting goals, working hard, and seeing results.
Physical fitness
Strength, flexibility, coordination, and stamina — built through fun, age-appropriate training.
Anti-bullying skills
Practical self-defense and the calm, confident presence that prevents most problems before they start.
A positive community
A respectful, encouraging environment where kids are celebrated for who they’re becoming.
Programs built for every stage of life.
From energetic 4-year-olds to busy adults — we have a class designed for you.
Little Dragons
Listening skills, coordination, and confidence through fun, age-appropriate movement.
Kids
Discipline, focus, fitness, and the foundations of traditional Taekwondo.
Teens
Leadership, mental toughness, and physical conditioning during the most pivotal years.
Adults & Families
Fitness, stress relief, self-defense, and a chance to train alongside your kids.
More than martial arts — a toolkit for life.
We live in a tough world. Social media, peer pressure, bullying — kids face challenges parents never had to think about. Every class reinforces the traits your child needs to thrive:
- How to stand tall and speak up
- How to handle conflict with confidence, not aggression
- How to set goals and follow through
- How to lead, not follow
- How to respect themselves and others
Taught by masters. Backed by a community.
Our Brookfield headquarters is led by Master Glazer — Wisconsin & Illinois State Sparring Champion, 7-time Gold Medalist at the U.S. Open Hanmadang Nationals, and Captain of the JK Lee Demonstration Team that performed at Milwaukee Bucks halftime shows in 2019, 2022, 2023, and 2024.
Every instructor on our team is certified, background-checked, and dedicated to helping your family grow.
“My daughter went from quiet and unsure to walking with her head up. The instructors here actually care about each kid.”
“Best investment we’ve made for our boys. Focus is up, attitude is better, and they actually look forward to going.”
“I joined with my son thinking I’d quit after a month. Two years later, we both train together. Best family decision we ever made.”

Common questions from Brookfield parents.
My child has never done martial arts. Will they fit in?
Absolutely. Most of our students start with zero experience. Our instructors specialize in helping beginners feel welcome and confident from day one.
What ages do you teach?
We have programs for ages 4 through adult: Little Dragons (4–6), Kids (7–12), Teens (13–17), and Adults & Families.
Do I need to buy a uniform to start?
No. Your $59 web special includes a free uniform that’s yours to keep — even if you decide not to continue.
How often should my child attend?
Most students train 2–3 times per week. We offer a flexible class schedule throughout the week to fit busy family life.
Is martial arts safe?
Yes. Our training environment is highly structured and focused on control, respect, and proper technique. Injuries are rare.
What makes JK Lee different from other martial arts schools?
Nearly 40 years in Brookfield, a Grandmaster-led curriculum, certified instructors, and a focus on character — not competition.
What happens after the $59 month ends?
We’ll sit down with you, talk about your child’s progress, and walk through your options. No pressure and no auto-enrollment.
