TGA launched its first Golf Enrichment Programs at six Los Angeles schools. TGA’s focus was to provide PK – 8th grade students with an opportunity to learn golf through an innovate 5 level after-school program. This program made golf affordable and accessible for children, and received an overwhelmingly positive response from schools, parents and students. TGA expanded its programs within Los Angeles area schools to accommodate the demands from students and parents who wanted a golf program within the safe, convenient environment of their schools. The curriculum also provided transition for students to go from their schools to programs at the golf course.


TGA’s first camps and clinics were offered at golf courses. TGA also incorporated the expansion of physical fitness and education components as well as adding a character development initiative within its school programs.


Golf professionals along with entrepreneurs began expressing their interest in the unique sustainable and scalable model of TGA. By the end of 2006, after three years of honing and improving the TGA business model and curriculums, TGA began offering geographically exclusive franchisees which became the TGA Premier Junior Golf Program now running throughout the United States.
