Antelope Valley School District

Principal's Message and Administration Team

It is my honor to serve as the Principal of Lancaster High School. On September 7, 1995, the first Lancaster High students walked onto our campus, donning a school uniform, ushering in a new era of the Antelope Valley Union High School district. Fast-forward almost 30 years later, I humbly lead a team that will continue to serve our Lancaster community as we give our best every day so that those we serve are inspired and empowered to become their true best.

From the first graduating class, this school has represented achievement and excellence and it is clear that our graduates demonstrate the ideals and traits that were envisioned 30 years ago. The long list of distinguished alumni from LnHS who have gone on to achieve extraordinary things testifies to this fact. You will discover that your four years at LnHS will move very quickly with all that this beloved and distinguished institution has to offer. I challenge you to take advantage of the opportunities you are presented with here at LnHS; make the most of your classes and extra-curricular activities and you will find that there will be very few limits to life after high school. Your future is what you choose to make of it; a future that begins right here by seizing the opportunities we provide for you at LnHS.

Our mission at Lancaster High School is to have our students embody our Graduate Student Profile...

Our students will become Creators, Collaborators, Communicators, and Contributors, every day. This frame encompasses everything we want our students to be able to do once they leave our halls.

Every class, club, activity, and sport we offer at LnHS has this core belief – empowering students to be poised to positively influence our community, nation, and world. At LnHS, critical thinking and problem solving combined with the Graduate Student Profile to become our “North Star” towards which we navigate each day with the goal of supporting you in the ability to find your path. We ask you to commit to giving your best, each day, at Lancaster High School and you will be poised to master your future.  We commit to you the ability to access all our programs and to provide you with a service-oriented school.

I am excited to lead this school and to have the opportunity to work alongside each of you and our amazing staff as we add to the great history of Lancaster High School. 

Go Eagles!
