    Hello! My name is Robin Tridico, and this is my 18th year teaching in Great Valley, and my 1st year teaching at the high school! For the past 17 years, I have been teaching 7th grade math at the middle school. I am excited to be working at the high school, and I am really looking forward to working with you on a new course!
