Student Leadership Team

*Note: Student Leaders are not Instructors, they are students who have demonstrated good values and qualities to be invited to the Student Leader Program (internship) to become future instructors. This program is broken up into three levels known as the SWAT (Special Winning Attitude Team), STORM (Special Team of Role Models) and the Mentor level. Each level is broken up into stages that the student must complete to enhance their leadership skills that will one day make them a great instructor and community leader. Whilst on the internship they assist the classes under the guidance of the Instructors.
