Shotokan Winnipeg involves family participation (parents and their children train together in the same class) On Tuesday and Thursday, classes take place at Parc LaSalle School in St. Norbert. The first class (6:30 p.m.) is for children 6-11 years of age and their parents, as well as individuals 12 years of age and over who have just started training. Basically, White to Green belts train in the 6:30 p.m. class. The 2nd class (7:30 p.m.) is an Intermediate/Advanced class for Purple belt level and higher. However, on Thursday, the advanced class is designed strictly for Brown and Black belts.
Although one of the most senior karate instructors in Canada, Sensei Loreth has kept the cost of instruction down to accommodate family participation. The style of karate that Sensei Loreth teaches (Shotokan) focuses on perfection of character, self-defence, sport and fitness. Respect for others is a very important element in his classes.
