The mission of GRETA is to work in partnership with the parks and recreation departments, schools, private tennis clubs, tennis professionals, children’s clubs, the North Carolina Tennis Association (NCTA) and the United States Tennis Association (USTA) to promote and grow tennis in Guilford County regional area. We seek to grow tennis through league development, school programs, public programs, special events and capital projects. Further GRETA will financially support community projects that either promote the sport or provide opportunity for under-served communities.
