Regional favorite Kwik Trip stresses groceries in its convenience stores. The vertically integrated chain controls costs and quality by producing and packaging its own items, from doughnuts and coffee to milk.

Private brands are at the core of the company’s business model. It has more than 300 SKUs of proprietary products. In 2014, stores began selling fresh meats, including hamburger, steaks, chicken and pork.

But it also stresses fuels, including alternative energies. Its first CNG location opened in April 2012, and Kwik Trip has continued to develop a functional CNG fueling infrastructure throughout Wisconsin, Minnesota and Iowa.

Kwik Trip, which also operates Kwik Star c-stores, is revered for its employee loyalty and retention, with a benefits package that includes profit sharing. The company has an on-site health services clinic at its headquarters for its more than 3,000 employees.
