Stephanie Guerreiro (OCT, B.Ed, BA)
Ms. Stephanie Guerreiro, or as we refer to her, Miss G, is in her eighth year on the Keystone School team. Miss G became a member of Keystone’s faculty as a Geography and History instructor in 2017. She now teaches middle school History and high school English and works closely with students on their university and college applications, helping students get into their dream programs as our guidance counsellor.
Miss G completed her Bachelor of Arts (History) at Trent University, and received her Bachelor of Education from Queen’s University. She spent the first five years of her teaching career working with students in Nanjing, China where she was able to explore her love of travel and experience different cultures.
Miss G loves working with students from international backgrounds, as well as those from closer to home, as they all have stories and experiences to share that make the world more colourful and fulfilling. Her favourite courses to teach are History and Geography, as they give everyone in the class a chance to broaden their worldview and learn about the world around them.
