Cannot say enough great things about Nathan and his studio. Started taking both our 8 and 6 year old about 3 months ago and couldn’t be happier. This is a non-traditional studio which is part of the appeal; no pressure to perform or hurry through belts. Also, he incorporates life lessons and skills into every lesson. Our son has some learning disabilities and Nathan’s class and teaching have given him self-confidence as well as the structure he needed. He has these great family fun nights, too! Super affordable. Best thing for me is that he has workout equipment and the parents can work out while we wait for the kids to finish their lessons. We will be lifetime members.

I cannot say enough great things about Kaizen Karate! I had asked friends for recommendations for karate and every single person recommended Kaizen. After our first day, I could see why. It’s my son’s first time doing karate and it not only is teaching him focus and skills, but the environment is so fun and perfect!

About Kaizen Tactical Martial Arts

If you're tired of martial arts studios only focused on selling you expensive and (let's be honest...) worthless Black Belts, or being forced to attend tournaments, and memorize forms, or putting up with instructors bragging about their rank, title, or style... Then KAIZEN: TACTICAL MARTIAL ARTS is your solution.

KAIZEN: Tactical Martial Arts in Reedsburg, WI offers Non-Traditional, Practical, and Effective Martial Arts training for Youth, Teens, and Adults. Discounts are given to Law Enforcement, Fire Rescue, Military, and Teachers. FREE Women's Self-Defense Seminars are open to the public as well.


Training is based on Real-Time application, Situational Awareness, Muscle Memory, Close Quarters Combat, and Concept Application... NOT by memorizing traditional forms and pretend self-defense techniques.

Classes are separated by age and skill. Youth classes are highly motivating, dynamic, and safe. Adult classes are entirely informal... this means No Uniforms, No Belt Rank, No Testing, No "Sir, Yes Sir" formalities. Techniques are based on the practical needs of adults (No impractical Hollywood techniques here).

Kaizen Tactical Martial Arts in Reedsburg, WI (Sauk County) utilizes boxing, striking, kicking, grappling, Submission, CQC (Close Quarter Combat), and tactical Knife and Stick Defense.

Classes are taught by Nathan Grey. Additionally he owns "I Am Cinema", which is a Video and Photo Studio focused on Cinematic Visuals.

Nathan Grey additionally works with Wisconsin Big Cat Rescue, working with Tigers, Lions, Leopards, and soon... Giraffes and Bears.
