Mark Oglesby: Upper School Government Teacher


What motivated and inspired you to teach? I was inspired by my English teacher, Mel Shields, who had such a passion for and command of his subject and cared about kids. I have always wanted to work with students because they are really our future. At 18 years old, I was coaching a little league team and loved the positive impact I had in their lives.

Why are you excited to come to ESD every day? The overwhelming sense of community makes me feel at home and a part of something important. Whether it is my colleagues, the students, the parents, or others, I truly feel that I am a valued and appreciated part of the ESD community. It is a nice feeling to have.

What life lesson do you want your students to learn in your classroom? In the classroom, I tell my students if there is only one thing you get out of my class, I want you to be critical-thinking citizens. I don't want them to be critical, but I want them to think about what is going on in our world and think about what they can do to make it better. And, of course, I want them to follow my motto, “Make wise decisions with the only life you have!”

What is a hobby nobody would guess you would have? I have become a massive soccer fan despite truly hating the sport growing up. When I moved to Dallas, I became a season ticket holder for FC Dallas. It is the first time I have ever had season tickets for anything.

If you could have dinner with three people, alive or not, who would they be? Theodore Roosevelt - my favorite president and would make the night interesting! Pat Tillman - a person I greatly respect for his sacrifice, and he was truly a thinker. Alexander Hamilton - such an important part of our nation's beginning and a visionary.
