I am thrilled to be the principal of Del Amigo High School and to be part of San Ramon Valley Unified School District. This is my twelfth year as a high school site administrator and it is a joy working the students and families of Del Amigo. 

I received my BA in Social Sciences from CSU, Sacramento, my MA in Education from Chapman University, and my Administrative credential from CSU, Sonoma. I have five children, three daughters and two sons; two Rottweilers and a cat; and I have been married 16 years. I enjoy suspense novels, movies, and television shows. And I love to camp.

It’s an honor to be part of the Del Amigo family. 

Kelly Estes, Registrar/Health Clerk

I was born and raised in Santa Monica, CA, and relocated to the Bay Area after college.  I earned my BS in Business Administration at University of the Pacific in Stockton.  I've been married since 1996 and now that my 4 children are self sufficient, I am back in the work force.  I started working with SRVUSD in 2013 as a substitute office clerk, and found myself at Del Amigo on day three.  I haven't looked back.  I love working with the kids at Del Amigo and I enjoy the small school size which allows me to know all of the students by name.

Outside of Del Amigo, I love to be active.  I enjoy competing in local tennis leagues and hiking with my husband and kids. I also love our 2 awesome dogs. 

Jon Sawyer, Counselor


I am originally from Texas, but grew up in Castro Valley.  I’ve lived in the east bay for about 25 years.  Before I became a counselor I worked as an EMT, as well as a travel agent, and in the real estate industry.

I received my BS in Counseling Psychology from William Jessup University and my MA in Counseling from Brandman University.  I have been in the San Ramon Valley Unified School District for just over 2 years and have primarily worked at Monte Vista High School, most recently with their Counseling Enriched program. I look forward to helping the students navigate high school and be prepared for success as they enter adulthood.

When I’m not at work I enjoy hiking, going to the movies, playing drums, cooking and baseball.

I bring to Del Amigo over 15 years of Administrative experience, 10 of those in an educational setting.

In the past, I have taught Kindergarten, ran a real estate office, worked in college admissions ,and did an internship at The San Joaquin County Juvenile Probation Department.

I am originally from Tennessee but grew up in California.  I have lived in the bay area for about 7 years.  In my spare time I enjoy playing with my crazy dog, gardening, wine tasting, and spending time with family and friends.

I am very excited to be part of Del Amigo High School.  I am here to assist you with Attendance, Parking Passes, Free/Reduced Lunches, and much more!

Thank you for allowing me be part of your child's learning experience.
