Train with Purpose

Kempo Karate is a practical self-defense art that blends modern effectiveness with traditional martial arts values.

At United Studios of Self Defense Lake Forest, students train in a disciplined, supportive environment where every class is taught with purpose, focus, and respect.

Our instructors provide personalized attention and adapt to each student’s needs, helping kids, teens, and adults build confidence, strength, coordination, and real-world self-defense skills.

More than Kicks and Punches

At USSD Lake Forest, the greatest impact of our training shows up beyond the dojo. Students become more confident and resilient—bringing the lessons they learn in martial arts into school, home, and everyday life.

MEET THE TEAM

Dragon Kath 
cHIEF iNSTRUCTOR

Sensei Dragon loves seeing students push themselves, overcome challenges, and grow through their training. Whether he is working with kids in martial arts classes, teens building confidence, or adults learning self-defense, he is passionate about helping every student discover their own strength and potential.

His own martial arts journey began at the age of 12 after a powerful childhood experience: seeing his brother being bullied and stepping in to protect him. That moment sparked a lifelong dedication to the martial arts and a deep belief in the positive impact self-defense training can have on children, teens, and adults.

Outside of the dojo, Sensei Dragon is a devoted family man and proud father to his 14-year-old daughter. He also enjoys working on motorcycles, bringing the same patience, focus, and attention to detail to his hobbies that he shares with students on the mat.

After 15 years of training, Sensei Aidan recently earned Sandan at the Tokyo Budokan. He’s proud to be a Sensei with autism and connects strongly with Lake Forest students on the spectrum. Off the mat, he’s an actor and dancer with multiple first-place finishes since age 10.

She loves seeing our Lake Forest Karate students having “aha” moments, and building a genuine love of learning. As a dedicated musician, she’s played violin for eight years in a symphonic orchestra and can play nine instruments.

Sensei Lana
Instructor

Sensei Lana has trained eight years and is known for creating a welcoming, caring, atmosphere where students settle in quickly. She balances structure with encouragement, and sets the tone for our community at USSD Lake Forest and recently earned her Shodan at the Tokyo Budokan. Outside the dojo, she enjoys volleyball and tennis.

Sensei Nick
Lead Instructor

Sensei Nick excels in personal instruction and spotting the details that help his students grow. His coaching is patient, positive, and practical. Fun fact: he crochets—from beanies to dolphins— he even made a seven-foot Christmas tree for the dojo.

"Will definitely recommend for people of all ages!"

"This studio has been such a blessing and Sensei Dragon is the best! We have one special needs child who has benefited physically so much from both a strength, flexibility and balance perspective, another child who lacked self confidence and has always been a little timid until he started at this studio, and a third son who has really learned to focus and stay disciplined from the lessons learned at the studio."
