About Me

I graduated from Trinity College, Dublin with a B.A in Medieval History before returning to Atlanta to get my M.A.T. in Math Education.  I’ve been working at Lakeside for 7 years and have sponsored Table Top Games for the last 3 years. I enjoy playing games, reading, trivia, statistics puns and memes, linguistics and cooking.  I have an adorable cat named Bizhiw who believes ardently that pens, pencils, and remotes have no place on tables or counters and does everything in her power to correct this universal wrong at every opportunity.
