    Principal - Mrs. Sara Harris

    It is my honor and pleasure to introduce myself as the Principal of Las Lomas High School.  I am truly honored to become reacquainted with the community and school that was an integral part of my own life. Having been a graduate of Las Lomas, it is still abundantly clear through the students, staff, and families I have encountered that the tradition and warm presence still exists within its hallways-“Once a Knight, Always a Knight”! I am looking forward to working with the dedicated staff, administration, and parents to provide the best possible educational programs for our students within the Acalanes Union High School District.

    I have been in the field of education for over 12 years as a Teacher, Coach, Curriculum Leader, and Associate Principal.  During my leadership career, I have learned the importance of core values and building strong relationships in order to establish clear goals and objectives throughout the school site. I have also had the opportunity to create pathways towards a positive school culture and have contributed to the development of programs that meet the needs of all students. I am elated to bring my skills as an instructional leader to Las Lomas and to work with you as a partner to ensure your child’s success.

    We will continue our work around curriculum reform, equity, inclusion, and connectedness for all students.  Through the various leadership teams at Las Lomas, our entire staff will provide differentiated instruction, interventions, and a level of rigor that promotes efficacy and the ability for our students to be active learners. A team approach is necessary to create and maintain a desired learning environment.  It is essential that we maintain this heightened sense of motivation and to ensure that every staff member, student, and parent is excited to learn what is happening on campus.  The positive attitude and culture will enable us to meet the challenges of academic excellence in a supportive environment.



    Associate Principal - Mr. Joshua Frishman 

    Mr. Frishman joined the administrative team at Las Lomas in the 2021-22 school year. Between the collaborative spirit of our staff and the goal-oriented mindset our students exhibit, Mr. Frishman is honored to be a part of this school. Entering his 15th year in education, Mr. Frishman previously served as an English teacher at Pittsburg High School. In addition, he spent two years as an adjunct professor at Saint Mary’s College in Moraga. As an educator, Mr. Frishman always keeps students as a priority. After all, aren't they the reasons we come to work every day? He looks forward to working alongside our wonderful staff in building an environment that promotes equity, integrity, and success!


    Associate Principal - Ms. Emily Woodall
