Principal's MessageTop of Page


Dear Lone Hill Families,

It is with great pride and excitement that I write this letter of introduction to you as the new Principal of Lone Hill Middle School.  My name is Jason Coss, most recently I held the position of Principal of Oak Mesa Elementary here in Bonita Unified School District.  Before entering administration, I taught at Shull Elementary, and prior to that I was a Los Angeles County Deputy Sheriff. 

Along with our outstanding staff, I will work hard to continue the legacy of success established at Lone Hill by building strong relationships with parents, students, staff and community partners.  This year we will focus on character education initiatives and 21st Century skills, along with fostering a nurturing and safe environment for children. Use of data will be utilized to drive instruction, and consistent implementation of direct instruction strategies will be a priority to increase student achievement.  In addition, Lone Hill will continue to afford all students exciting and challenging enrichment opportunities.

During the course of the year, it is my hope that we will work together to provide the students of Lone Hill the best possible opportunities; thus preparing them to be world class citizens ready to master the challenges of the 21st Century with a solid foundation created here at our school.  As Principal, my door is always open and I welcome your input.  Please feel free to stop in, email or call to make an appointment to discuss any concerns, suggestions, or ideas to help make this the best year yet!

I look forward to getting to know you this year and ask for your continued support and personal involvement with Lone Hill Middle School in the weeks and months ahead.

Look forward to meeting you all!

Jason Coss
