My journey with College of the Siskiyous began at age two, when I volunteered to be a simulated patient in the EMT/Paramedic program. I've been involved with COS ever since, and have always known that I would begin my college experience here. I would tell anyone considering attending COS that it's a small campus, which makes for a tight-knit community in which you’re able to really have meaningful interactions with fellow students and faculty. Everyone is super helpful here!
