Welcome to the Los Osos High School Grizzly Den website.

We are located in the city of Rancho Cucamonga
 in Southern California.  Los Osos is part

of the Chaffey Joint Union High School District.  The coaching staff, led by head coach

Kevin Price,
welcomes all visitors.  Whether you are a player, parent, grandparent,

coach or a fan, we hope
you will find the information on the website useful and informative.

 The website will be used to inform the Los Osos Football family and fans about our great
Football organization.  This website has been created with the help and financial support of the
Los Osos Football "Grizzly Den" Booster club.  The 2015-2016 Grizzly Den Board of Directors,
 would also like to extend their welcome to all who visit this website.
Please visit the "Grizzly Boosters" webpage to learn more about our Booster Club.
