Haven't had any in any official capacity. I've had a number of people I've leaned on over the years as a source of guidance and people I can toss ideas around with. I think a lot of it does come down to personal experience in business. Learning through doing. Reading helps a tonne too. 

A few years back, I had a guy who I referred to as a mentor in business.. Anthony Amos, founder of Hydrodog. He opened my eyes to the world of entrepreneurship and all its possibilities. Simply through sharing his story.. we'd touch base now and then. So in that respect, he was super important. Without him, I'm not sure I'd be in business!
