Towering centre half signed from St. Kevin’s Boys during the summer of 2013, making his first team debut against Dundalk in a Leinster Senior quarter final tie.
Sean has represented the Republic of Ireland at Under 18 and Under 19 level. He proved he had the ability to make the step up during his time with the B team in 2014 and added to his experience while out on loan with Shelbourne during 2015.
Sean finally made the breakthrough to Pat Fenlon’s side the following season and kept his place under new manager Stephen Bradley. Always a threat at set pieces, he scored 4 goals in 22 appearances that year.
