For almost 15 years I have been a self-employed graffiti artist working under the name of Olas Art, which comes from my name Nick Halahan (Nicholas - I thought it was about time I used the Olas part!) I do commissioned artwork for people and businesses, while delivering graffiti art workshops for young people and community groups. I have painted murals all over the UK, from Edinburgh to Exeter, and internationally from Mexico to Spain. I am now based in Bristol, UK after many years working in and around West Yorkshire.

Whether I am painting for myself, or for someone else, my artwork often includes bright colours and some kind of movement flowing through. This was something I picked up when painting a lot of graffiti letters, where my aim was to bring the letters to life bending them into satisfying shapes and giving them a character of their own.

I started delivering graffiti workshops for young people when I was volunteering at a youth centre in Leeds, where I was the Regional winner for Yorkshire & Humber Vinspired National Awards 2009, and national nominee for Most Inspirational Volunteer. Since then I have taught in schools, children homes, HMP Eastwood Park in South Gloucestershire and secure units including the Atkinson Unit, Vinny Green and Adel Beck Secure Children's Home.

I have delivered graffiti art workshops in NHS mental health institutions such as the Roycroft Forensic Unit in Newcastle, Fromeside adults ward in Bristol and Lavender Walk in Kensington. A career highlight has been working with Leeds GATE (Gypsy And Traveller Exchange) on and off over the last 8 years, and delivering art workshops to Irish traveller sites across Leeds, Bradford, Wakefield and more recently Bristol.

I am currently doing a lot of graffti workshops across the whole of Bristol, particularly in St Pauls, Hartcliffe and Knowle West with youth groups like CYN, LPW and Young Bristol.
