Welcome to Mr. Schlegel's class!

This is my 6th year teaching Math at McCollum High School.  I grew up in Southern California and went to Loyola Marymount University in Los Angeles, California where I earned a Bachelors Degree in Electrical Engineering.  After college I was commissioned as an officer in the United States Air Force, where I proudly served for 22 years before retiring in 2012.  I had always planned on becoming an educator following my military career and I'm glad that I finally found my way to McCollum High in San Antonio, Texas.  Go Cowboys!

We have an exciting year ahead of us as we set out to learn and master the subject of Algebra 1.  Our class will be challenging yet fun as students will learn through exploration and discovery.  By working hard and persevering, we will be prepared to apply principles of Algebra to other high school math and science classes, to future college studies, and in everyday life scenarios.

I can be contacted at  I am always available before and after school to answer students' questions and to provide assistance. I look forward to personally getting to know each student and helping prepare for a future of success.
