Background
After graduating from the University of North Dakota with a bachelor’s degree in General Management, I worked as a carpenter for eight years. At the end of this period, I decided to go back to school to become a teacher. Subsequently, I earned a double degree in Middle School and Secondary Education. By this time I had decided to continue my education in mathematics. Two years later, I had completed a master’s degree in Mathematics. To further my education, I transferred to Montana State University where I earned my doctoral degree in Mathematics Education.

Interests
My interests are geometry, history of mathematics, world history, and Eastern religions. I teach courses ranging from Intermediate Algebra through to Algebraic Structures.

Philosophy of Teaching
The purpose of a university is to prepare students for the real world. To do so, my method of teaching is to provide guidance and gradually place the responsibility for learning on the students. Students are taught to ultimately become responsible for their own learning and reach a balance between independent study and collaboration with classmates. Specifically, I create an environment that encourages student interaction in the classroom.
