Mr. Alan Klein

I graduated from the University of North Texas with a bachelors in Social Science. I spent my first six years teaching world history and coaching football at Clark High School in Plano. For the last two years I led the world history team and helped write curriculum for the district. This year, I took on a new role as Haggards Head Football Coach and Athletic Director. I also teach PE, where I can help kids gain a passion for living an active lifestyle. I truly love helping kids from all backgrounds and abilities succeed academically and athletically. My wife, Amy, is also a world history teacher in Plano and we have an awesome 3 year old boy and 6 month old daughter. When teaching my students, I always think about my children and how I would want them treated.
