He is an Irish household name having worked as a fashion presenter and designer for over 20 years primarily but in his new RTÉ documentary Brendan Courtney gets personal.
His life, and that of his family, changed dramatically when his father was left paralysed on the left side of his body following a stroke 18-months-ago.
Since then the family has grouped together to take care of former builder, Frank to meet his needs and wishes.
After a little digging, Brendan found out that you can get money for nursing home care through the Fair Deal scheme but that funding does not extend to care in your own home.
The Courtneys are now campaigning to Leinster House to change the rule so that Frank, and others, can stay at home, as he and his family wish.
Watch the promo below and you will see that this was a tough programme for Brendan and his family to make but as he has said, it is an important one and one that Frank wanted to make to help others who are going through the same thing.
We Need To Talk About Dad is on RTÉ One tonight at 9.35pm.
