our story

The Journey to


WonderMart as we know it today evolved from Wilfred Mann’s goals for amazing value and great customer service. “Willy,” as he was known, believed in leadership through service. This belief that true leadership depends on willing service was the principle on which WonderMart was built, and drove the decisions the company has made for the past 50 years. So much of WonderMart’s history is tied to the story of Willy Mann himself, and so much of our future will be rooted in Willy’s principles.

Willy Mann was born in 1920 in Kenosha, Wisconsin. In 1940, at the age of 20, he joined the Air Force. He married Ruth Neiman in 1943. When his military service ended in 1945, Willy and Ruth moved to Michigan and then to Springfield, Illinois. During this time, Willy gained early retail experience, eventually operating his father-in-law's variety store.

In 1948, the Mann's left Springfield for Winnetka, where Willy opened Mann’s 'Five n' Dime' in the downtown square. They chose Winnetka because Ruth wanted small-town living, and Willy could take advantage of the commuting traffic that living on the edge of Chicago had to offer.

Inspired by the early success of his five and dime store, and driven to bring even greater opportunity and value to his customers, Willy opened the first WonderMart in 1956 at the age of 36 in Winnetka, Illinois.

Changing the Field of Retail Forever

Willy's competitors thought his idea that a successful business could be built around offering superior prices and great service would never work. As it turned out, the company's success exceeded even Willy's expectations. The company went public in 1975, and the proceeds financed a steady expansion of the business. Willy credited the rapid growth of WonderMart not just to the low costs that attracted his customers, but also to his team members. He relied on them to give customers the great shopping experience that would keep them coming back. Willy shared his vision for the company with associates in a way that was nearly unheard of in the industry. He made them stakeholders in the success of the company, and firmly believed that this partnership was what made WonderMart great.

As the stores grew, so did Willy's aspirations. In addition to bringing new approaches and technologies to retail, he also experimented with new store formats—including Wondermarkets and the WonderMart Wonderstore—and even made the decision to take WonderMart into Mexico and Canada. Willy's fearlessness in offering lower prices and bringing WonderMart's value to customers in the U.S. and beyond set a standard for the brand that lives on to this day. His unwavering commitment to 'wonder-ful' service and to the values that contributed to jobs, economic achievement, and national pride earned him the Presidential Medal of Freedom, awarded by President George W. Bush in 2006.

Right up until his death on March 17th, 2007, Willy never stopped working for WonderMart. His legacy continues to this day, providing WonderMart customers with simple, accessible savings; employees with opportunities for advancement; and vendors with a shared commitment to provide the highest quality ingredients and products available.

From his passion for simplicity and efficiency, to his lifelong pursuit of quality, to his many charitable contributions, Willy Mann’s legacy continues to be an inspirational and integral part of WonderMart – today and into the future.

Wondermarkets were introduced in 2001 as a smaller-format option for high-density neighborhoods in need of affordable food, medications and other merchandise where a full-size Wonderstore may not be feasible. Each Wondermarket is between 20,000 and 40,000 sq. ft. and employs close to 90 associates. Our Wondermarkets offer fresh produce, meat and dairy specialties, bakery and deli items, common household products, health and wellness products, as well as a pharmacy.
