Tensions are brewing between a minor shareholder and a pair of majority owners of a Charlton, Massachusetts-based brewery.  Viewed as one of the most well-known and best tasting craft beer producers, Tree House Brewing Co. is ranked among the top breweries around the world.  Since 2011, owners Nathan P. Lanier and Damien L. Goudreau claim to have worked endlessly on nights, weekends, and holidays to grow the craft brewery to what it is today.  Despite their efforts, the last remaining minor shareholder, Eric Granger, is accusing Lanier and Goudreau of rewarding themselves excessively.
