Sabrina McManus

I am originally from Massachusetts. I also spent time growing up in Florida and North Carolina. I studied Psychology, Math, and Education, receiving both my Bachelors and Masters from the University of North Carolina at Chapel Hill (go Tar Heels!). I am excited to be a Phoenix and support the DHMS math department. I love making connections and building positive relationships with students. I love making learning fun, hands on, and differentiated to meet and challenge all students. I have been teaching in the northern Virginia area since 2018, with experiences in both middle and elementary schools. Prior to moving to Virginia, I spent time teaching in Beijing, China; Chapel Hill, North Carolina; and Hamburg, Germany. In my free time, I like to play soccer and volleyball, travel, paint, and read mysteries.
