Tim O’Donoghue - Principal

I have worked for the Tustin Unified School District in a wide variety of jobs since 1980. During this time I have worked at the high school, middle school, and elementary school levels. For the past 7 years I have served as the principal of Hillview helping give kids a second chance so they can graduate. When not in school I enjoy coaching youth sports and volunteering in the community and at my church.

Katherinne Valdovinos - Principal's Secretary

My name is Katherinne Valdovinos A.K.A Mrs. Kathy! I’ve been working for the Tustin school district since 2015, but have been working with children since 2008. I received my ROP certificate in Early Childhood Education and began to work in the Yuba City Unified School District in Northern California as a teacher in the After-School Program. I then became the Attendance Clerk for two years at an elementary school before moving to Orange County. I started as a part-time interpreter for Tustin Unified District and then became the Community Liaison for Hillview High School and recently accepted the position of Principal's Secretary here at Hillview High. I plan to attend Santa Ana College in the fall and transfer to a university to graduate with a degree in Family and Consumer Sciences.
