This a great place to train! Nathan, the owner, provides a one-of-a-kind environment for learning self defense that is practical in real situations. Classes are fun, motivating, and reflect positively on other aspects of life. Nathan caters each session according to the people that come and how quickly they learn. I highly recommend this business to anybody of any skill level who is interested in martial arts, self defense, and/or fighting.

If you are an adult who has always wanted to get into fighting but has felt awkward or unsure of where to begin, look no further. Nathan provides a learning experience that feels fun and easy and won't make you feel foolish. Also the gym itself is worth visiting as he has created a temple of serenity filled with life and art. Cool place, cool people.

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.
