A father and son operation founded in 2009 by John and Mike Shea, this family roastery in Traverse City, Michigan roasts exclusively on American made Diedrich equipment that has expanded from a 7 kilogram roaster to a 70 kilogram capacity. The Sheas developed their roasting skills and production capabilities gradually, investing in larger equipment as demand grew while maintaining their commitment to small batch roasting standards. Mike Shea's represents the classic American roasting story, where family dedication and quality focus create a loyal customer base across both retail and wholesale channels.
