Raul Castorena / Social Worker

I’m the Social Worker at Hillview High School.  I grew up in Santa Ana, Ca.  At the age of 19 I made the decision to join the United States Navy, I felt the military could give me the discipline I was missing, and it did.  I served 4 years in the Navy which included time overseas during the war in 2003.  The Navy is actually where I started my college education, I took college classes on board the ship.  When I got out of the Navy I continued my education at Santa Ana college and Santiago Canyon College, I then transferred to Vanguard university where I got my Bachelor of Science in Psychology.  A few years later I went back to school and earned my Master's in Social work from USC.  I’ve always had a strong desire to support my community and I use social work to do so.   The biggest thing I can say to our students is, have a vision for yourself and don’t be afraid to fail, failure was my best teacher.

Karen Ramirez - Community Liaison / Language Specialist

My name is Karen Ramirez or Ms. Karen! I recently started working for Tustin Unified School District but have worked with children since 2014. I began at the YMCA program for the Anaheim School District as a program leader. I then accepted a position for Santa Ana Unified as a Biliterate paraprofessional teaching students how to read and write in both English and Spanish for four years. It was such a rewarding job, but I always wanted to work for a high school which led me to my current position as the new Community Liaison for Hillview High School. I am grateful for the opportunity and happy to be working with such a great team.

I’ve been working for the Tustin Unified School District since 2006. I was first hired as an office Assistant for the Nutrition Services Dept where I processed over 4,000 Free and Reduced Lunch applications. I then re-located to Riverside County for a year and a half and left Tustin District. After that I ended up relocating back to Orange County because moving out there was not a good idea. After my return I was hired as a Nutrition Assistant, serving students lunches where I worked there for about 6 years. In Spring of 2016 I was hired as an Office Assistant for Adult ED which I enjoyed a lot and met a lot of great people. Winter of 2017 came and I became a Community Liaison at Hillview and in 2022 I was promoted to Attendance Clerk at Hillview High School. I really enjoy working between the Students, Parents and Community I feel grateful to work with such a great team.

It has been a privilege for my husband, Bill, and myself to live in Tustin and to have raised our two daughters within TUSD. I spent my earliest years in the mid-west, and have mainly lived in Orange County since 1962, attending public schools in Orange, California. I attended Covenant Bible College in Prince Albert, Saskatchewan, Canada ( a one year certificate program), and later worked as Dean of Women there for two years. I graduated from North Park College, Chicago, Illinois in the bi-centennial year, 1976, with a K-8 teaching credential and a BA in Social Studies. A number of other work experiences include fifteen years of insurance claims as an adjuster and supervisor,teaching pre-school while my children were young, and presently finishing my eighth year at Hillview High School as a paraeducator/ RSP aide. My passion is good literature and reading, and I enjoy helping our students become better readers and writers.
