About Castro Valley Sports Foundation
Castro Valley Sports Foundation (CVSF) was founded in 2002, all volunteer-based, non-profit 510(c)(3) California organization that provides charitable assistance and support youth sports and athletics in Castro Valley. This fundraiser event and any sponsorship dollars will go directly to help widen and sustain sports participation in our community.
As CVSF pursues its commitment to raise funds for sports and athletics in Castro Valley, here is how CVSF has given back to the community:
In 2010, the CVSF donated $26,500 to the CVUSD to help fund all sports at CV high school and closed a CVUSD budget gap of over $250,000 that otherwise would have eliminated all high school sports at Castro Valley High School for 2010-2011 school year.
In 2008, the CVSF donated another $16,500 to various interscholastic sports programs at Castro Valley High School. The money was distributed in 17 grants ranging in value from $300 to $1,500 and included all girls and boys programs such as: storage container for track and field, electronic scoreboard for wrestling, pitching machine for girls' softball, place clock for swimming, helmets for football, and training equipment for soccer.
In 2007, the CVSF donated $4,500 for the purchase of a portable batting cage for the CVHS baseball program.
The CVSF donated more than $180,000 towards the CVHS football stadium project
Most recently between 2011 – 2021, CVSF has donated between $15,000 - $28,000 yearly through the grant program to different youth sports organizations and teams from CV Little League, Canyon/Creekside Middle School Tennis Program, Elementary Schools Track Programs, CV Track Club, CVSC Top Soccer Program and numerous CVHS sports programs.
CVSF invites local businesses to become a sponsor for this event. For sponsorship details, please contact Rachel Lunt at teamlunt07@gmail.com.
