For the month of March (also known as Irish American Heritage Month) IrishCentral is tapping into the heartbeat of the Irish American community. The Unsung Heroes series features inspiring individuals from across the US who do extraordinary work in their communities and respective fields. From advocates to artists, from local legends to dedicated educators; from a high school baseball team to dynamo nuns in their 80s, these people are making a difference and to them we tip our hats in thanks.
