Megan is a high school teacher in Atlanta, Georgia, USA. She founded the Global Math Department, an online professional development community of around 1000 math teachers who meet in weekly webinars to learn from each other. Megan hosted her first webinars way back in 1998, when users had to dial a toll free number for the audio because internet connections didn't have enough bandwidth. These days, she and fellow teachers share lessons, start new projects, and maintain one of the strongest online communities around.
