Seth Contreras

Hi! My name is Seth Contreras, and I started here at Oswego High School in 2019 teaching Biology and Chemistry. I don't know many people can say that a single person changed their life, but I can, and that person was a teacher. From that moment, I decided that if I could do THAT for others, that would be the most worthwhile way to spend a career.


Other facts about me: My favorite biology topic is genetics. My favorite chemistry topic is atomic structure. I have worked for Walgreens for 12+ years as a Senior Pharmacy Technician. I have attended College of DuPage, Benedictine University (B.S. Biology), DePaul University (M.S. Biology), and Lewis University (M.A. Education).
