Allied Midwest Merchandisers, Inc. was founded in 1959 by a group of forward-thinking independent lumber dealers in the region, who were looking to increase their purchasing power in order to be more competitive in the marketplace.  Out of their efforts to work together, AMMI was born.

From these humble beginnings, AMMI grew in size and scope over the years.  The original ownership structure was cooperative in nature, but the business evolved over time to become what it is today, a full line two-step wholesaler of quality lumber and building products.  Almost three decades of growth led to the need for a more expansive facility, and in 1988 AMMI’s current location was purchased.  Located near the I-229 and I-90 interchange, there are over 10 acres of inventory to choose from, making material pick up at AMMI’s facility both easy and convenient for its customers.

AMMI also maintains a large modern fleet of delivery vehicles for moving products efficiently to the various customer locations it services in a 4-state area.  Both lumber and building products can be mixed on the same truck, making AMMI a “one stop shop” of convenience.  Regularly scheduled delivery days each week means customers can count on AMMI to be there on time with the products purchased, as promised.  Friendly, knowledgeable drivers arrive with customer orders carefully packaged and positioned on the truck to insure quick and easy unloading.

Over the years, AMMI has grown into one of the leading full-service building material wholesalers in the region.  Strong partnerships with our customers, mills, and manufacturers helps AMMI continue to grow each year in ways that even the founders could not have envisioned.  A staff of industry veterans helps propel the business forward as well, employing new technology and cutting-edge ideas for servicing our customers.  Many years ago, AMMI was formed as a way to help independent lumber dealers – today that mission is still at the center of who we are and what we do.

AMMI is continuously improving, focusing on ways to leverage purchasing power and assets in a way that benefits the customers we serve.  Close personal relationships are still driving growth, as they did in the beginning.  And even though AMMI has incorporated all the latest technology to optimize efficiency in every aspect of its business, you can rest assured an actual person will cheerfully greet each caller, a personal touch we feel cannot be improved upon.

Yes, there have been many changes throughout the company’s history, but our core values remain the same…fast and accurate deliveries, quality products and service, overall value and personal relationships.  These are the cornerstones on which AMMI was founded, its something we’re proud to bring everyday to our loyal customer base, so that together, now as in 1959, both prosper.
