Wisconsin Firefighters mentioned in a Guiness Beer Commercial. Greenfield, WI Firefighters were sent to a home for a cardiac arrest patient who was shoveling during a snow storm. Firefighter/Paramedics from the Greenfield Fire Department revived the patient and were not done there. They returned to the scene and shoveled the gentleman’s driveway. A great effort by Firefighters is now recognized in a commercial by Guinness Beer. Nice Job Brothers!
