The Medford Public Library is co-sponsoring an online conversation with Boston/NBC 10 sports journalist Trenni Casey, host of “Arbella Early Edition.” Casey has worked in the sports journalism field since 2000, in Milwaukee, Pittsburgh and Boston, and at the national level for the MLB Network, ABC Sports and the Big Ten Network. She’ll discuss how she got to where she is, what it takes to be a sportscaster in New England, especially as a woman, and the current state of Boston sports.
