Mr. Steve Leonard

I retired from US Army Intelligence (I oxymoron) after 22 years of service. I'm married to another veteran with two boys that both graduated from PSHS (2009 and 2013).  I have an awesome German Shepherd named Sasha that I incorporate into my classes whenever possible!   My service and my travels took me around the world and in the process I’ve learned German and Russian.  I've attended a half a dozen universities and studied chemistry, geology, and history. After my service, I worked as an industrial chemist for Henkel Corp and a management consultant for AT&T for a number of years before leaving corporate America to follow my true passion: teaching at the only school where I would ever want to teach: Plano!  I feel that my varied life experiences give me a unique insight to how the world works and I hope to convey that to my students.  My goals for all my students are to understand how their country came to occupy its unique position in the world, to learn how to be responsible citizens in a democracy, to think for themselves, and to be able to express those thoughts in a clear and intelligent manner.
