Born in Brookly, Kieran has lived in Ireland for nearly 26 years. Her son, Tadhg is born and reared here and has provided huge support to Kieran as she moved from the NGO sector into baking. Prior to beginning her baking journey Kieran worked for Amnesty International for 20 years heading the Campaigns and Activism team.

In 2022 she undertook a Commercial Baking training program led by Adrian O’Connor and tutored by Rossa Crowe. Following the course Kieran and spent time working in a bagel bakery in NY to learn the ins and outs of authentic NY Bagels. In 2024 she launched fatbaby Bakes from her home microbakery, providing authentic NY bagels to her neighbours and community. Since launching, Kieran has introduced a variety of bagel classics - the everything, sesame, poppy, onion, garlic and seasonal specials like pumpkin spice, mince pie and cranberry nut bagels. In a nod to her former career Kieran has also introduced a bagel inspired by the flavours of Palestine, all monies from which go directly to food aid in Gaza, a blending of her passions for baking and for human rights.

Kieran continues to explore different flavours that she hopes to bring to her bagels and her schmears. She also continues to engage with her community and support causes she holds dear.
