She has just completed a Level 9 in Social Policy in TCD. She works as a Care Policy Offcer lobbying for better care from Early Years to Older Persons to Disabilty Support.

Eilish is best known locally as a teacher and manager of Happy Days early years centre based in Ratoath Community Centre. During her ten yeals there, Eilish and Happy Days won a number of awards for excellence in innovation and teaching. In 2021 she was shortlisted by Early Childhood Ireland for Pedagogical Leader and she came second.

Happy Days has been featured for its work on TV, radio and in the print media locally and nationally.

Eilish also worked for a number of years as a Special Needs Assistant or SNA, so the field of education was not new to her when she began studying to become an early years teacher. 

Eilish has also been active as a volunteer in Ratoath Community Centre. She started and worked on a number of successful projects, including the Community Christmas Show and Fair.

In 2022, she initiated further projects - one to restart an Alzheimer's Social, the other to facilitate young people who want to learn skills around repurposing clothes - called 'Flipping Fashion'.

In 2022 she won the LMFM Community Hero Award in recognition of her work during the Covid-19 pandemic. 

She started up the Country Market in the Community Centre.

Other groups she is active in include Ratoath Tidy Towns, Ratoath Rugby Club, Rathbeggan NS Parents’ Association, and the Facebook Group Ratoath Needs a Community Voice which was set up to campaign for a play park on the unused HSE site in Ratoath. 

Eilish has been to the forefront of the SIPTU Big Start Campaign which was started to achieve a formal pay structure for staff in early years eduction.

SIPTU appointed her as one of its negotiators for the first ever national pay negotiations for this sector.

In 2022, the negotations ended in agreement on a new national pay structure that has a legal basis through the first ever 'Employment Regulation Order' for the early years sector.

Eilish is a powerful advocate for the recognition of the importance of early years education and for tackling the low pay that is endemic in the sector.

She has addressed conferences and rallies on this, including conferences organised by SIPTU and the National Womens Council of Ireland.
