All In Baseball

You must be ALL IN if you want to succeed in life!

All In Baseball (AIB) was founded in 2022 with the goal of creating a better baseball community in the greater Atherton area. AIB is a 501(c)3 non-profit which is geared to enable today's youth to go All In on their lives.  Through community out reach, on field camps & clinics, mental performance classes and baseball essential skills,  All In Baseball will help you be better prepared for success in life. 

Every year, AIB offers camp & clinic scholarships to youth from underprivileged backgrounds in the East Palo Alto, East Menlo Park and Redwood City areas.

All In Baseball is proud to partner with The Miracle League of Redwood City to create a better sense of baseball community in the Bay Area. Members of AIB will help The Miracle League remain a world class organization!
