Dr. Christopher Whitt hosts "Margins," a WVIK podcast featuring conversations with change agents from around the Quad Cities area, as well as across the country. These discussions focus on groups of people who are marginalized politically and socially, and the people working to provide change for those communities. "We need to take the time to have these conversations so people can hear new perspectives — so people who are doing the hard work, who are leading, who are trying to push for change within the community as well as making a better world overall, can have a voice," Whitt says. "Margins" is produced by Lacy Scarmana .
