Steve came to O’so in the very early days, late Spring 2009, after losing his job at a printing company . He worked in every facet of the brewery from bottling to cellar work and logistics.

Sales and Marketing

Dylan Buttera

Dylan is Marc and Katina’s eldest son and has a young growing family of four. Dylan has always been a learner and an achiever, and so he has started a screen-printing side business in the last few years that he tries fitting in, alongside his job of traveling the state of Wisconsin, working the market for the O’so brands. He has been working in the family business for since Summer of 2010. He has always enjoyed reading, being outside and most of all making money. He was once almost suspended from school in Junior High because he had turned his locker into a convenience store in between class periods selling jolt energy drinks and cheap candy. He was actually making quite a bit of money until a certain health teacher shut him down since his products weren’t to her health standards. More than anything though, Dylan often enjoys a good stimulating conversation of the sort that most people don’t care to have. Venturing into forbidden territories and getting outside of one’s comfort zone are what make a lesson stick he says. Therefore he believes in challenging the status quo and playing devil’s advocate quite often. Go ahead try it next time you see him! (2018)

He was ready to get back in the beer business, so he left the dental industry in 2016, moved up to the great state of Wisconsin and landed the Beer Ambassador position with Tyranena Brewing Co. He was with them for close to two years before joining us here at O’so on August 6th, 2018.
