The Kaizen Karate Team
"Kaizen" is the Japanese term for “continuous improvement,” and we believe that epitomizes what Karate and self-defense training is all about. We opened our doors in 2014 with a mission to bring the wonderful life skill of self-protection to children and adults alike in the Windsor area.
Shihan Matt Schildt
Shihan Matt Schildt, 49, the owner of Kaizen Karate & Self-Defense, has been a martial artist for 26 years.
Before opening Kaizen Karate & Self-Defense in 2014, Schildt trained in Karate and Tae Kwon Do from 1984-91, then resumed his karate training in 2005 under Master Charles Orchard at Total Ryu Martial Arts. Schildt taught for three years under Orchard in the Total Ryu children's karate class, and also trained for five years in Orchard's Adrenalized Confrontation Training (ACT), which is regarded as one of the best practical self-defense programs available, and has been taught to police and military personnel.
In 2016, two years after opening his own school, Schildt joined the Colorado Karate Association (CKA). He began training under Grand Master Jerry Davis, Grand Master Ben Ramsey, and Master Todd Jonas. With their guidance, SchIldt has grown Kaizen Karate & Self-Defense into one of the CKA’s premier martial arts studios — including producing 14 CKA State Champions in 2022. Grand Master Davis (9th Dan) promoted Schildt to 5th Degree Black Belt and Shihan (Master Instructor) in March 2021.
