Denielle Finkelstein Put the Product Where the Problem Happens

Mark Hellendrung
Mark Hellendrung is the Rhode Island native who bought a fading 1890 beer brand for less than $100,000 and made it New England's again. As owner and CEO of Narragansett Brewing Company, he resurrected a lager that had nearly vanished, brought brewing back to Rhode Island after a 30-plus-year exile, and opened a waterfront brewery and beer hall on the Providence harborfront. Before beer, he ran Nantucket Nectars and coached the team at Magic Hat. His pitch has always been the same: stay homegrown, stay local, and don't sell out to the big guys.
