Our second semester is off to an excellent and fast paced start!

Our students are getting a fresh start and have begun their semester with a lot of energy and optimism.  Our school utilizes a lot of technology in the classroom and we will continue to incorporate it as we move forward.  We are excited to open our new stadium in 2016 and hope to have events in the stadium this winter.

Please keep in mind a few points to support students’ achievement this semester:

  • Tutoring takes place after school from 2:30-3:30 Monday-Thursday
  • Our library is open from 2:30-5:00 p.m. Monday-Thursday
  • School Loop will allow you to view students’ grades and progress in their classes
  • School Loop will also provide you an opportunity to contact teachers via email.
  • If you need assistance in any of the above, please contact our Guidance office.

It is crucial for our students to stay focused and attend school every day. We are here to support them and work with our parents and our community to help create paths that will lead to our students’ success in college and careers.

It is an honor to serve our students as their Principal, please do not hesitate to call if you have suggestions and ideas.
