Hello Jaguar Community,

We are off to an excellent start to the new school year!  Our students are well immersed in their classes and many are participating in after school activities and athletics.  We are very fortunate to have incredible facilities for our students.  We have an enormous amount of technology for students to learn along with Wi Fi for them as well.  

I encourage you to stay connected to your son/daughter’s high school journey.  We encourage you to attend athletic events and student activities.  You may also join us for “Coffee with the Principal” and visit our Student-Parent Impact Center which offers numerous parent education classes (the schedule/calendar is found under the resources tab above).

Thank you for your continued support and for partnering with us to bring about the best educational experience for our young Jaguars.  You may follow me on Twitter @OntarioHS to stay connected to our school community!

We are preparing our students for college and careers!  Go Jags!


Mr. Zaldivar



All Ontario High School students will graduate ready for college and careers.
