Mark is a pioneer in Minnesota brewing.   Summit Brewing began in 1986 out of St. Paul–well before microbreweries were able to sell their beer from a tap room.    As of 2020, they are the 21^st largest craft brewery in terms of sales volume in the United States.    Mark talks about how he got started, some guerilla marketing he did early on, and the power of relationships and making a difference in your community.
