Miller Resource Group was originally founded as Sales Consultants of Oak Brook in 1970 by the late Donald W. Tobin. As one of the earliest franchises of MRINetwork, then Management Recruiters International.  The firm's original charter was to recruit and place sales and marketing executives.

In 1985, a highly successful Account Executive at the firm, Gary Miller, purchased the office from Tobin. Since that time, Gary has guided the firm to become one of the premier offices in MRINetwork.

Many of our original clients were Sales Executives, whose career success had catapulted them to General Manager or CEO. These clients continually asked us to expand beyond sales and marketing in the areas of finance, operations, engineering, manufacturing, and management. Responding to these market demands, the firm ultimately acquired two additional MRINetwork divisions that now serve our clients' needs by finding nearly any kind of candidate, for any function, in any industry, anywhere in the world.

In early 2004, the firm's name changed to Miller Resource Group, to simplify our brand strategy.
