Hello, I'm Eric Henninger.
I have been at Garden Grove High School nearly my entire life. I took swimming lessons here at a young age, then volunteered as a swim lesson assistant during summers while I was in middle school (Ralston). I then went to high school here and competed on the swim team. After graduating in 1995, I spent summers here teaching swimming lessons, and after a couple years, in 1998, I became the head coach of the Argonaut swimming and water polo teams. I have been coaching ever since. I also worked as a Computer Resource Assistant here while I was going to college to become a teacher (2000 - 2007). In 2006 I got my teaching credential and student taught here, and in 2007 I was hired as a teacher.
I've been teaching AP Computer Science A since 2010 and added AP Computer Science Principles in 2016.
