T4 TRUST - Key Persons


Aaron Mulhern

Job Titles:
  • Member of the Executive Team
  • Head Teacher - Ian Mikardo
Aaron was educated at St Joseph's Secondary School in Derry City, Ireland. His experience there gave him a meaningful, positive grounding in the value of others, a sense of always working towards being a better person and contributing whatever talent he had to the benefit of the community and society. His hope is to live up to that aspiration. In Derry, Aaron learned that the value of education isn't about 'being the best' but being 'your best'. He feels lucky to have experienced some wonderfully committed teachers working in difficult circumstances, setting him on the path of emulating their example. In 2003, after studying at St. Mary's College in Strawberry Hill, Aaron had the opportunity to work at IMHS and did so for three years, as the Numeracy & Literacy coordinator. He then left to train as a Physiotherapist. Aaron has always been captivated by the ethos, spirit and practices of IMHS school and so he jumped at the chance to return in 2012. He accepted the position as Teacher of Maths and has had roles as leader of the 'My Passport' Dept.; Deputy Head Teacher; and now leader of the school. Aaron's aspirations for the school mirror the aspirations of his own teachers in his formative years and those of IMHS, hitherto lead by Claire Lillis since 2002. Aaron believes in the importance of recognising the value and talents of the students and staff in our community and helping them grow through their challenges, in pursuit of a meaningful and purposeful future. He is committed to supporting our students who come with a past, to leave with a future.
