Known for both his pioneering artistry and high profile clients, ranging from Tupac to David Beckham, Lana Del Rey and Jhonny Depp - the latter of whom he starred opposite in the critically acclaimed Black Mass- he was Introduced to the art of tattooing as a teenager and spent years studying the work of artists in Rhode Island and New York, trying to learn their secrets. Working hard, Mahoney toiled in other tattoo salons before opening his own shop in 1985 - only to lose it within four years to a crippling heroin addiction. He later moved to Los Angeles where he finally created The Shamrock Social Club, defined as “Where the Elite and the Underworld Meet.” It’s that unique and inspiring combination of high-art and low culture that captures the Warrior Spirit that identifies Mahoney’s take on life.
