About Us

Kaizen Karate was founded by Coach V in 2003.  Kaizen Karate has been offering instruction in non-traditional Tang Soo Do as part of its core curriculum.  Over the past few years, American Kenpo has also been introduced into the system.  Kaizen Karate's team of highly trained martial artists offer a number of programs for students starting as young as 3.5yrs old up to adult.  They focus on discipline and encouragement in a fun-loving environment.  Their main goal is to help everyone progress, continually improve, and enjoy the process.

In 2014, Kaizen Karate expanded to include Kaizen Run Club & Kaizen Athletics.  All youth & adult programs now fall under the Kaizen Fitness umbrella.  Kaizen Fitness now operates 7 days per week throughout Maryland, Washington D.C., and Virginia.
