Weis Markets was founded as Weis Pure Foods in 1912 in Sunbury, Pennsylvania by brothers Harry and Sigmund Weis.
The Weis brothers opened a second store in 1915 in Harrisburg, Pennsylvania. This store became strategically important to the chain as it grew as the regional anchor for the Pennsylvania market.
By 1933 the chain had grown to 115 stores, all in central Pennsylvania.
Starting in the 1960’s Weis Markets, as it was then known, began to expand into neighboring states Maryland and New York, and later to Virginia and Washington, D.C.
Today Weis Markets operates 165 stores in Pennsylvania, New York, New Jersey, West Virginia, and Maryland. The stores sell groceries, dairy products, frozen foods, meats, seafood, fresh produce, pharmacy, deli, bakery products, food and wine.
Weis Markets is publicly traded on the New York Stock Exchange under the symbol WMK, is #770 on the Fortune 1000, has 18,000 employees, and had $2.69 billion in revenue in 2013.
