The Addison Community Athletics Foundation (ACAF) is a supporting 501(c)(3) organization of the Vermont Community Foundation. It was established in 2012 to promote athletics and healthful behaviors throughout the region by supporting tennis and other health education programs for youth and adults.

​

ACAF's mission also complements the Vermont Community Foundation’s commitment to building philanthropic resources that will sustain healthy and vital Vermont communities now and into the future. ACAF owns and operates Middlebury Indoor Tennis where many youth, adult, and school tennis programs take place throughout the year. Since starting outreach efforts, ACAF has partnered with many Addison County schools and local organizations to help them access the sport of tennis.
