Greetings! My name is Mary Pat Sheppard, and I am a full-time math professor at Malcolm X College. I received my bachelor’s degree from the University of San Diego and my MS from Northeastern Illinois University. Through those years of study and because of the wonderful professors I had, I developed a love for mathematics. It’s a way of thinking that continually provides challenges and has beauty in its patterns and language.

I have been teaching at MXC for 20 years; before that, I taught at St. Xavier University and Moraine Valley Community College. Altogether, I have been an educator, both part-time and full-time, for about 40 years. I consider myself very lucky to be in a field and a college that I thoroughly enjoy.

Outside of work, my life is busy with family, friends, and pursuing interests of travel, wellness, and reading. I consider learning to be a lifelong occupation that makes living richer and more interesting. I always tell my kids, “If you love to read, you will never be bored!”
