Meet the Business Owner

Sander V.

Business Owner

Sander has been practicing sports his entire life. These consist of mostly martial arts (since the age of 7) but also semi-​professional cycling in Belgium, triathlons, weight lifting and overall fitness training.

During his martial arts career, he has been extensively trained in Wado Ryu Karate and Japanese Ju Jutsu. Throughout the years, he has also added Mixed Martial Arts and Brazilian Jiu Jitsu to his skillset. His approach to self defense was taught to him by chief combative instructors of the special police forces in Belgium and it is his goal to create a purely realistic and effective program for people who wish to learn how to maximize their fighting skills and safety.

Throughout his bachelors in Physical Education, Personal Training and Sports Management, he has also been trained in countless other individual and team sports as well in the anatomy and physiology of the human body.
