O'Callaghan is an outspoken supporter of suicide and depression-related topics,[1] having had previous personal experience of these throughout his adult life.[2] He has written books dealing with such topics,[3] and was a supporter of the Irish suicide charity Console Suicide charity Ireland before its closure,[4] representing them in Dáil Éireann debates on at least one occasion.[5] O'Callaghan is a qualified clinical psychotherapist.[6]

In 2010, O'Callaghan spoke out against cocaine use following the death of Gerry Ryan, a former colleague and friend.[6][7] He acknowledged that he had known of Ryan's cocaine use for 16 years[8] and received criticism and intimidation after speaking about this in public.[9]



O'Callaghan started with small pirates such as Radio Dublin. He then was a presenter on "superpirate" Radio Nova in the early 1980s, followed by Sunshine Radio (briefly), later Energy 103FM and Q102 (briefly). He spent a few years on UK radio, after his spell with Sunshine Radio in 1983, starting with offshore pirate Radio Caroline.

After Q102, O'Callaghan joined legal Irish radio with Millennium Radio and then in 1989 he moved to the newly relaunched "2fm" – an attempt by RTÉ to steal some of the thunder of the recently departed Superpirates. He then presented the very popular "Gareth O'Callaghan in the afternoon" show which was similar in theme, tone and content to The Steve Wright in the afternoon show on BBC Radio 1 of the late '80s and early '90s.This show was a huge success gaining O'Callaghan widespread popularity all over Ireland by offering a brand and style of commercial radio that was more reminiscent of Radio Nova in Dublin at the very height of its popularity.

O'Callaghan left RTÉ 2fm's afternoon show, having previously presented the breakfast show on the station (replacing Ian Dempsey). His afternoon slot is now occupied by Rick O'Shea's eponymously named show. After leaving 2fm, O'Callaghan took some time out from radio to pursue a career in psychology before being named presenter of the breakfast show on Galway Bay FM. On 27 February 2009 Gareth launched Ireland's newest commercial independent Quasi-national radio station 4fm where he was the morning show host before moving to the afternoon slot.[10]

Before Gay Byrne's retirement from The Gay Byrne Show in 1998, he was helped a bit by O'Callaghan but O'Callaghan left him after getting fed up and went to RTÉ 2fm instead. Des Cahill had to help Byrne after that.[11]


O'Callaghan has been writing since 1995. To date, he is the author of six best-selling works – five novels and a memoir. He has contributed two stories to the New Island Open Door series, entitled Joe's Wedding and Stray Dog.[12]

New Island publishes literary fiction, poetry, drama, biography, politics and social affairs. O'Callaghan wrote A Day Called Hope: A Journey Beyond Depression about his own personal experience of severe depression. The book detailed how, as soon as left his radio job each day, he would retreat to his bed, sometimes with thoughts of suicide.[13] It became one of the biggest-selling books in Ireland in 2003, and continues to sell in huge numbers. It has been published in 15 countries, and translated into 10 languages.

O'Callaghan is also a regular contributor to many of the national newspapers in Ireland, having written regularly for The Irish Times, the Sunday Independent and the Evening Herald. He is currently writing a sequel to A Day Called Hope, and is also said to be working on a new novel.

Personal life

He lives in Cork, dividing his time between Dublin and London. He has three daughters called Kerri O'Callaghan, Katie O'Callaghan and Aibhín O'Callaghan.


In March 2018, O'Callaghan announced to listeners of Neil Prendeville's Cork's Red FM show that he had developed Parkinson's disease (PD). He said: "I was tripping. I was dropping things in work. When you drop a cup of coffee literally out of your hand and it scalds your foot and people look at you and think 'what's wrong with him?' I fell out of the bath one morning and I didn't understand why I fell out. I have noticed changes in you have to stop and choose words. It is not that your speech changes the way you transport the words it happens in a different way. When I was diagnosed I was told I have had this for a couple of years which in a way was a relief to me. There were times over the last few years where I thought I was going mad. I couldn't figure out what it was." O'Callaghan mentioned that, prior to his diagnosis, he had read a Daily Mail article in which DJ David Jensen spoke of his experience of Parkinson's.[14]

O'Callaghan retired from radio in August 2018 after being diagnosed with the neurodegenerative illness multiple system atrophy (MSA), an incurable and even more rare disease (less than 3,500 people were at the time thought to be enduring the condition in the whole of Ireland and the UK). In an online post, he wrote "It is a rare disease, very progressive and sadly incurable. I thought I might have been able to continue working as normal for another few months but, unfortunately, the pace and the painful decline of this awful thing has really taken us by surprise."[14]
