Community Support Makes Stack Possible

★

Sonoma Stack Baseball is a nonprofit 501(c)(3) organization committed to building character through competition for young athletes in and around Sonoma Valley.

Our program began in 2009 through the generous support of the William Moore Stack Foundation. Today, Sonoma Stack serves nearly 100 players from ages 9 to 18, providing competitive baseball, player development, and a positive team environment rooted in attitude, energy, effort, and family.

Sonoma Stack is an all-volunteer organization. We rely on our families, sponsors, and local community to help fund the program and keep participation as accessible as possible for players.
