I owned and operated martial art schools for 15 years in Georgia. Separate classes were offered for children ages 6-9, youth classes age 10-16, and adult classes age 17-60.
As the owner, I was responsible for all aspects of business management including such things as marketing, training staff employees, curriculum development, and all fiduciary responsibilities. The business functioned as an S corporation.
The main school was sold in 2000 and is still in operation in 2025. I maintain a business relationship with the school currently, and do business consulting for them.
