The Dennehy School of Irish Dance has been in existence for over 40 years. It was first started by Dennis and
Marge Dennehy. Many of the Irish dancing teachers in the Chicagoland area were pupils of Dennis and Marge.
Their most famous pupil by far starred in shows such as Riverdance, Lord of the Dance, and Celtic Tiger (and was also the 1975 Senior Boys Under 17 World Champion)––Michael Flatley. In 2005, Dennis and Marge were inducted into the North American Feis Committee Hall of Fame. The school is now under the direction of Dennis and Marge's daughter Kathy. Kathy was a championship dancer herself and began teaching at the school when she was in her late teens. A former championship student of Kathy's, Kathie Moloney-Horan, now teaches at the school. The Dennehy Dancers compete in local, regional, national and international competitions where they have attained great success––the most recent being that of Michael Putman, Boys 16–17 2009 World Champion. The Dennehy Dancers perform annually at Ireland on Parade and Irish Fest, both at Gaelic Park in Oak Forest, Illinois and Celtic Fest in Grant Park. They have also performed in Dance Chicago at the Athenaeum Theatre in Chicago. Many of the Dennehy Dancers have performed with the traditional Irish musical groups The Chieftains, Cherish the Ladies and Mick Maloney.
