The recently-retired Kerry footballer left his job in St Brendan’s College, Killarney, in 2010 to enrol in a fashion course in Dublin Institute of Technology.
He has since launched a website through which he markets a barber shop and men’s hair products.
“There were just opportunities happening and I had a small presence online and it kept growing and growing,” explained Galvin. “I didn’t know if I could, to be honest. I just took a punt, really.
“I make a decent living. It’s not like I’m making, you know... but it’s better than what I earned teaching.
“There’s more to be done there, but a year-and-a-half, two years ago, there was no guarantees that I would do anything with it. I just kind of said I’d go for it and see what happened.”
Galvin has no regrets about leaving behind his teaching profession and is in the process of securing further deals with companies in Dublin, London, and New York.
He believes other inter-county footballers and hurlers can follow his example. “I think other GAA players should be doing it as well, because you could see social media becoming a course module in university, or even second level.
“You have social media with economics, with languages, with sociology, psychology — there is a whole world there that I think could be tapped in to.
“For me, it has basically become full-time. It’s hard to tell people — it’s basically online advertising through social media.”
