Derek Devoy's life changed in November 2014 after he stopped two people killing themselves in just one night when he was driving around Kilkenny city in his taxi.
Derek was shocked to see a man standing on a bridge ready to jump, and managed to get him down and into the car, where he then called to gardai for help.
Less than two hours later, he saw another man on the same bridge about to take his own life. Derek also managed to talk him down, saying that having suffered from depression himself, he knew what he was feeling.
That night moved him so much that Derek did a SAFETALK and ASIST (Applied Suicide Intervention Skills Training) workshop, found 21 taxi drivers in Kilkenny who wanted to help as much as he did, and set up TaxiWatch.ie.
The group patrol the streets, bridges, and quays of Kilkenny in their taxis looking for people who may be in distress.
