On "Beyond the Classroom", we talk to people who use their platform to teach others. From self-taught woodworkers and urban gardeners to roller skaters and craft brewers, we meet people who have turned their passions into careers.

This week we spoke with Christina "Fritz" Stang, a San Diego local, life-long rollerskater, and owner of Fritzy's Roller Skate Shop in Mission Beach. We talk about her introduction to skating, how her passion developed into a lifestyle, and how she now uses her expertise to teach others.
