He moved to Maine in 1978 and worked a dozen years in commercial radio in Sanford, then Portland, before beginning to freelance for Maine Public Radio in 1990. He has been the local anchor of Morning Edition since September 1992.
Irwin served as chairman of the Maine Association of Broadcasters in 2015. From September 2004 to October 2005, Irwin served as national president of the Society of Professional Journalists, the nation’s largest and most broad-based journalism organization. He holds a master’s in journalism from New York University. Irwin won a Yankee Quill Award in 2011 for from the New England Newspaper and Press Association for his “broad influence for good, both inside and outside the newsroom.”
Irwin also has an interest in astronomy, which he indulges to this day as an occasional show presenter at the Southworth Planetarium in Portland. And he swims, a lot. Irwin has completed 7 Peaks Island-to-Portland swims. Irwin is married and has a teenage son.
