Mrs. Irish Mahan

Welcome to the 2018-2019 school year! This is my second year at Prosper High School and my 18th year in education.  I am super excited to be teaching World Geography and look forward to meeting my classes!

I received my Bachelors Degree in history from UC Davis with a minor in religious studies, and I received a Masters Degree in Education from the University of LaVerne. I've also had the privilege of traveling extensively, including studying abroad with UCLA in Greece and Turkey.  I consider myself to be a life long learner and I'm constantly seeking out opportunities to grow as an individual and an educator.

My family and I moved to Prosper, Texas three years ago.  I have a wonderful husband, and two great kids that attend Prosper schools.  My husband and I enjoy coaching our children in Prosper Little League and grabbing slushes at Sonic.  In our spare time my family enjoys traveling, golfing, boating, and playing sports!

I am looking forward to a fun and successful year!
