Last Updated: 2015-06-03

Over 100 employees work at the Academy, all on a part-time basis (no full-time employees). Directors oversee the operation of all activities by way of communication with Department Chairs who are responsible for the operation of their departments and all of the Programs therein which are administered by Program Heads. Within each Program are Projects and Events that are conducted by numerous faculty and staff. Among the Faculty, Instructors teach PE/Recreation (and academic) classes and Coaches mentor team training (Coaches are certified as both judges and coaches and conduct practices with team athletes who pay annual tuition). Business operations are conducted by managers who work various shifts during the day. A Day Manager is responsible for all business activities for that day (e.g., the Monday manager is responsible for closing out all financial activities and is the main point of contact for events occuring on Mondays). Students are those attending classes or receiving contracted instruction while Clients are those paying tuition for the classes or contracting services. Participants are those who engage in the events, activities, classes, workshops, clinics, seminars, conferences, etc.  Players (or gymnasts) are students (or non-students) who belong to sport teams and compete in their sport (using Hawaii Academy training facilities).  Below are descriptions of some of our employees:

She was a US national champion and has competed as a senior elite in many international competitions including famous meets in Holland, Russia, and Denmark. She loves recreation classes and is probably responsible for promoting more students from recreation classes to competitive teams than any of our 55 employees. This past year she was responsible for 27 athletes competing at the USAG Trampoline-Tumbling Junior Olympic Nationals Championships in Chicago, which produced 36 top ten finishes, 12 medals, and eight national titles. She was also the event coordinator for teams traveling to the San Diego Open in January and the USAG Trampoline-Tumbling Region 2 Championships (also in San Diego) in June.

She applies her technical knowledge as a former state and regional level artistic gymnast, state and national trampoline champion, international trampoline competitor, and high school cheerleader, with her love of teaching, to make her classes as fun and educational as possible. In the office, Mia serves as an assistant director, day manager, and technical writer.

Since then she has acquired business operations skills for running nearly all systems and served as head of personnel. After finishing her degrees she took a position as a full time human resources manager leaving less time available to work at the Academy. Now she fills in for day managers and continues substituting as a director when Dr Max, Dr Mah, or Coach Justine are away.

After teaching Physical Education at various YMCAs and Long Beach Unified Schools, he has been a wonderful addition to the Academy's staff, always willing to do more than just teach. And when he's not busy engaging kids in his classes, he enjoys spending time with his wife and dog, gardening, and pretending that he knows how to play guitar well.

Recreational Instructor & Receptionist.

A 2005 honors graduate of Kamehameha High School where she was a springboard diver and previous gymnast, Teacher Joelle can be seen working in the office when help is needed, teaching a variety of preschool, beginning, and intermediate classes, and just being an all-around team player. Her dedication to teaching what she knows to her students has made her a well-liked and popular instructor at the Academy. She is currently a sophomore majoring in Economics at the University of Hawaii-Manoa, but if she's not there or here at the Academy, she is probably spending quality time with friends or at the beach just hanging out.
