Bachelor of Science - Northern Illinois University

Mrs. Jacqueline Lettenberger (McGinn)

In 2013, I graduated from Northern Illinois University with cum Laude honors and my Bachelor of Liberal Arts and Sciences degree. I majored in Mathematics with an emphasis in Secondary Education. Out of college, I taught for two years at AlWood Middle-High School. I taught grades 6-8, as well as an Algebra 1 course to freshmen and sophomores. After two years of being at AlWood, I decided to move back home in order to be closer to family. In 2015, I was hired here at St. Joseph High School and haven’t looked back since. This will be my fifth year at St. Joseph where I will be teaching all levels of Geometry, as well as Pre-Calculus Honors.
