We're O Positive.

O Positive is more than a slogan for us.
It's our way of telling a story of the many

1st Annual

Ontario High School will be putting on their first annual community Tiger Boo Bash/ Trunk or Treat on Monday October 31st, 2016. We are hoping to provide another location to our community where our young children can have a safe, secure, family friendly environment to trick or treat. Our generous staff and parents have signed up to decorate their trunks and give out candy. We are still in need of volunteers to set up their trunks and give out candy. As you are well aware, we have a very big community here in Ontario. Events like these help us give back to our families and increases community and family engagement in other activities and meetings. Please contact Mrs. Figueroa @ 889-5309 ext 1084 to sign up or if you have any questions
