About Us

An industry-recognized leader for more than 40 years, Mary Ann’s manufacturers and distributes high-quality, high-valued branded meats that are trusted family-favorites handed down from generation to generation. We process and produce smoked, cured, and uncured (nitrite and nitrate free) meats including hams, bacon, sausages, poultry, beef, as well as a variety of prepared items.

William Korleski began the family business more than 40 years ago in Klemme, Iowa. His ability to prepare the finest seasoned and smoked meat products became rapidly sought after and his business soon flourished. In 1978, he built a new 20,000-square-foot facility, began focusing on smoked meats, and created his famous Kor-Bert brand, most notably a ham in both bone-in and boneless pit style that is the premier ham in the Midwest.

In 1993, to keep up with growing demand, Korleski relocated his company to a 70,000 square-foot complex in Webster City, Iowa, where it still resides today. Mary Ann’s (named after Bill’s wife) has maintained its time honored processes using the highest-quality and freshest ingredients available. Their old-fashioned curing and smoking methods, and handcrafted processes, result in flavorful and distinctive meat products that truly are in a class of their own.

With the capacity to produce several hundred thousand pounds a week, Mary Ann’s custom processes nationally recognized brands and private label award-winning meats for customers across the US. We sell to retail, foodservice and wholesale operations under many well-established brands.

As a family owned business, we take pride in delivering healthy, wholesome, exceptionally delicious meats. We work with suppliers that raise their animals with respect and time-honored practices.
