    Principal's Message

    Grizzly Nation,

    We are beyond excited for the upcoming school year and I am humbled and honored to be the Principal at Los Osos High School.  Los Osos was built upon the motto, excellence is a habit and this has been the foundation of our school since we opened our doors back in 2002.  This foundation has resulted in 17 years of Grizzly excellence in academics, athletics, arts and activities.  Our vison is that all students will graduate ready for college and careers. This is what drives us to maintain our focus on providing effective classroom instruction, increasing student achievement and providing all students with a safe and equitable school environment to foster their individual growth.

    Parents, you play an equally important role in the success of both your student and our school. We encourage you to emphasize the importance of student learning and daily attendance with your child, communicate often with our teachers who are here to support all of our Grizzlies and register for your parent School Loop account so you can regularly monitor your student(s) grades, many of their assignments and academic progress.  We believe in WE>I, meaning working together we will accomplish so much more than working as individuals. These are key ingredients to a successful school.

    I am extremely excited for the 2019-20 school year and we look forward to seeing all of our Grizzlies back for the first day of school which will be on Wednesday, August 7th at 8:05am!  It is going to be a fantastic year Grizzlies! 

    Claws Up!

    Mr. Joshua Kirk
