Linda Lane has a daunting task: shepherding the city’s school district through some of its biggest challenges in history while remaining a hands-on educator.

When a trusted grad student told us about his "brilliant and pragmatic" social media professor at the Katz Business School, we bit.

As part of the "Coming Home PA" series about returning vets, presented by PublicSource and Pittsburgh media partners, Pop City offers a powerful story about homeless veterans finding their way through Shepherd's Heart. This organization has served as a lifeline to many vets, including one who now works there, Chuck Webb, who just won first prize in the recent PSVP Fast Pitch contest. (He got the standing ovation that night.)
