Twin brothers Jeff and Tom Heinen are the owners of Heinen’s Fine Foods, a grocery store empire started by their grandfather in Shaker Heights 90 years ago. They have nearly 20 locations in Ohio and four more outside Chicago. Their customer base is large and loyal, something the twins cultivate with award-winning stores and their own Two Brothers line of specialty products. We talked to the brothers Tuesday outside their Chagrin Falls Plaza Drive location and discussed how they're keeping business going in the day and age of Amazon Prime. They also discussed the future of their stores, and whether shoppers can expect expansions into more markets.
