Katie Grennan Playing Fiddle

Katie Grennan's traditional fiddle playing carries the articulation of a gifted classical musician tempered by the soul of a champion Irish dancer. Her wide ranging experience as an international touring performer in both live stage productions and television have given her a unique platform as an ambassador for the music of her heart. 

Born and raised in Wexford, PA though residing in the Chicagoland area for over a decade, Katie was the fiddler in the popular celtic-fusion band Gaelic Storm for over five years, has recorded a number of solo albums, and currently plays in a number of  musical projects at the forefront of the Celtic and Irish Traditional genres, including Reverie Road, The Bow Tides & Chicago-based STEAM Quartet.  She has also appeared regularly with artists such as Aoife Scott, The Trinity Irish Dance Company, Riverdance singer Michael Londra, The Prodigals, and more. In 2024, Katie was awarded Female Musician of the Year by Chicago-based radio program Ireland Tonight. 

As a highly sought-after and dedicated instructor of both traditional music and dance, she works with fiddlers of all ages and levels both in-person and virtually. Numerous students of hers have qualified for and received top three medals at the All Ireland Fleadh Cheoil on fiddle dance tunes and airs, and in 2024, she received the Gradam na hEigse award for her teaching work by Comhaltas in Ireland. Having passed the TCRG Certification with honors in 2010 from An Coimisiún Le Rincí Gaelacha (the largest worldwide governing body of Irish dance), she has held a position as a lead instructor at the Trinity Academy of Irish Dance based in Chicago. Her deep knowledge of Irish dance & musical prowess makes her one of the forefront musicians on the Feis scene (Irish step dance competitions), and she plays regularly for championships around the country. Her recordings tailored especially for Irish dancers can be found on the Feis App.

Katie is committed to sharing the gift of music with others. She is the current Executive Director of Sharing Notes, a Chicago-based non-profit that brings joy and comfort to hospital patients through the power of live music. She also serves on the board of Murphy Roche Irish Music Club, a registered branch of Comhaltas Ceoltóirí Éireann. Katie holds a Masters in Arts Management from Carnegie Mellon University and a B.A. in Accountancy and Psychology from the University of Notre Dame.
