Our Family

Brentwood Martial Arts & Fitness is a member of the Z Ultimate Self Defense Studio.

A family of martial arts companies formed with one goal in mind – to provide “Z-Ultimate” martial arts experience for students and their families by providing life changing and character building experiences through world-class personalized martial arts instruction. It is the largest martial arts company of its kind, with locations in the Midwest and on the West Coast.

What is unique about Z-USDS – besides it’s Dynamic Mastery Method™ of instruction – is that it is NOT just an association or license, where any martial artist can pay a small fee and use the rights to the logo and attain certification. There are many such organizations that boast hundreds, even thousands of members with this model.

With a philosophy of leadership that teaches, “Be a product of what you represent”, every single staff and support member of the Z-USDS family are martial artists and train actively. By doing so, we never are “out of touch” with what is happening in our locations because we are students, too.
