With varied roles on stage across several genres, from the World Premiere of Frank McGuinness’s adaptation of Ibsen’s GHOSTS at Bristol Old Vic, to Arthur Miller’s DEATH OF A SALESMAN at the Gate Theatre in Dublin to Tania in the World Premiere of Marie Jones’ SINNERS at the Lyric Theatre in Belfast and a whole host in between, Séainín has racked up an impressive array of theatre credits and has tread the boards of some of the most prestigious theatres throughout the UK and Ireland to rave reviews.

Swapping theatre for the screen, Séainín was named ‘Woman of the Year in the Arts’ for her portrayal as Francis in Ronan Bennett’s BBC political conspiracy thriller HIDDEN, opposite Philip Glenister.

Séainín can currently be seen portraying Anna McVeigh in the new Netflix original series HACHE and as Liz Tyler in the psychological thriller THE FALL alongside Gillian Anderson and Jamie Dornan.

She has just finished filming Steven Knight’s major new drama for the BBC, directed by Paul Whittington.

Outside of acting, Séainín supports many local and international causes and has personally raised more than £100k for Hospice Care in Ireland.

She started acting when she was 8 years old and worked in theatre and television until the age of 16 when she took a break to focus on her education.

After leaving Methodist College Belfast, Séainín read a BA Honours Degree in European Studies with French and Spanish at the University of Ulster. She then earned a scholarship to read a Master’s Degree in European Political Administration at the College of Europe in Bruges, before becoming a stagiaire at the Secretariat General of the European Commission in Brussels.

Following her work at the Commission, Séainín worked briefly as a political lobbyist in the private sector in Brussels representing large global companies. It was during this time that she realised she was on the wrong journey in life. So she packed her bags and headed off to Drama School choosing to attend the Guildford School of Acting in Surrey and she never looked back.

Similar to her own approach to life, Séainín favours playing real women. Women who have a story to tell. When interviewed, she states time and time again that she loves playing truthful, honest, real women. Women of conviction.
