O'Keefe Implement is a family owned and operated business that was established in 1916 by J.E. O'Keefe and his brother Pat. Originally located in Yale, South Dakota they relocated due to the depression of the "Dirty Thirties" to a location near De Smet, South Dakota. Since 1970 the implement has been operated by J.E.'s granddaughter Kaye, her husband Greg, and their son's Shawn and Tony.

In 1994, O'Keefe Implement purchased the Case IH store in Brookings, SD and operates under the name Brookings Equipment in the Brookings Ag Plaza. The dealerships offer a complete line of Case-IH farm equipment, precision farming parts and service, along with Artic Cat ATVs, UTVs, numerous short line farm equipment and Ford Motor Company vehicles in De Smet. 

O'Keefe Implement will celebrate it's 100th anniversary in 2016 and look forward to serving our loyal customers for years to come!
