Greetings! My name is Ryan Callan, I am a Math and Science Teacher from the University of Toronto. I grew up in Toronto where I enjoyed learning about how the Universe works, and find that the more answers you get the more interesting questions pop up. I have worked in a nuclear power plant, a hospital in Thunder Bay and at the University of Guelph, but I have been teaching since 2012 with no end in sight. I wake up in the morning with a smile on my face, ready to enrich the lives of my students who are the world's future.
