He has won many prizes at the prestigious Oireachtas na Gaeilge Irish Language Arts Festival. Currently, two of Ógie’s books, “Cúpla” and “Katfish & Scéalta Eile”,  are on the Irish Junior Cycle Curriculum and are the most sought after texts for Irish teachers around the country. In 2019 Ógie made history as his book “Katfish & Scéalta Eile” became the first ever Irish Language Book for young people to break into the Nielsen Top 10 Charts, alongside giants of the literary world J.K. Rowling and Jeff Kinney. For a number of years previous to that, Ógie’s Junior Certificate History textbook, An Cúrsa Iomlán Staire, was the staple diet of Junior Cert students of the old history course in Ireland’s Gaelcholáistí. 

Ógie is a relation of Irish Language literary giants, Nuala Ní Dhomhnaill, the late Professor Pádraig Ó Fiannachta, the Blasket Island poet, Seán Ó Duinnshléibhe and is the son of the famous Limerick singer from Castleconnell, Ann Mulqueen. An expert in his field, Ógie has a forensic knowledge of the Irish Language, a knowledge which he democratises and shares with students of the tongue. He is often called upon by state organisations to advise and upskill Irish teachers countrywide.
