After spending his childhood in residential care, Irish street artist Liam Grennan has overcome a lack of self-confidence to learn how to master his art. No matter how much raw talent you may have, it always takes a bit of hard graft to truly master an art form. One person who learned that the hard way was Liam Grennan, a young Irish street artist whose life was turned around when a former art teacher named Dominic helped him get back on track. As a child, Liam was moved from foster home to foster home. After leaving rural Longford for the southside of Dublin city, he became transfixed by the incredible street art he found on nearly every corner. For Liam, street art is something that opens a whole new world of creativity. A lack of self-confidence can be enough to stop anyone in their tracks, and it wasn't until he met Dominic that Liam started to get his confidence back. Now as a 23-year-old who has worked on projects such as the 3 Arena VIP area, Chopped in Smithfield, and plenty more, Liam can rightly say that is something he has overcome.
