Founded in 1963 as Phil-Rich Ag 
Service, Phil Benner and Richard Oloffson saw an opportunity to begin a feed business in western Bureau County. Shortly thereafter, Dick Oloffson purchased the other half of the business and renamed it Rich’s Ag Service. Adding a fertilizer business in the late 1960’s, Dick took his first step into the agronomy sector. By 1979, Joe Michlig joined forces with Dick, and the business stepped further into retail chemicals, trucking, and grain drying. In the early 1980’s, a grain site was added just south of Manlius on IL Hwy 40, to be followed with a bulk LP and fuel in the years to come.
Joe Michlig’s son-in-law, Don King, joined the company in 1983. In 1988, Joe purchased the business from Dick, and renamed the business Michlig AgriCenter, Inc. 
Don gained experience in various areas of the business and eventually became General Manager. In 1993-94, a facility was added in Cambridge and a chemical containment shed was built in Manlius. Two years later, Don purchased the company from Joe.
Don continued to grow the business in the years to come as he bought NBC Grain in Cambridge (1999), TWAG in Walnut 
(2000), added CGB Sheffield (2002), and Franklin Grove (2004). In 2006 grain facilities were added in Bradford, Broadmoor and Mineral. With the addition of these facilities, Michlig Ag now employs over 70 full time staff, many of whom have been valuable employees for several years.
Don and all of Michlig’s employees are committed to serving our customers in the following sectors: fertilizer, seed, crop protection, custom application, grain marketing, LP and fuel, crop insurance, feed, and trucking.
Today Michlig AgriCenter’s facilities are much different from the original business founded over forty years ago; however, our message and goals remain the same.
We believe that our business philosophy is different from most Ag retailers. We are committed to responding to the needs of 
our customers. Our focus is to provide service and products that bring value to their businesses. In addition we strive to increase our customers’ profitability by providing agronomic consulting from Certified Crop Advisors and customized marketing programs from certified grain merchants. As a company we seek opportunities to generate revenue for the communities of our customers.
The employees of Michlig AgriCenter feel a sincere commitment to their customers and their local communities. They have a strong desire to be the best supplier and they are eager to be involved in their communities through volunteerism.
We pledge to continue adapting and growing to fit our customers’ needs, and to assist our communities where we live and do business.
We are grateful to our existing customers who have allowed us to be a part of their business, and we look forward to earning the opportunity to serve new customers.

Owner, Michlig AgriCenter, Inc.
