Jeff Cole grew up on a farm a few miles north of Madison, South Dakota, where his parents still live, and where he loves to visit. Jeff and his wife Kim now live in Sioux Falls, but he still longs to live on the farm. His wife Kim is not so sure about that, but may be persuaded someday. Jeff does own his own tractor that he keeps on the farm, which allows him to drive around and at least feel like he is a farmer for short periods of time.

Jeff graduated from Madison High School in 1979, South Dakota State University in 1988, and the University of South Dakota School of Law in 1992.

Jeff joined the Zimmer and Duncan law firm as an associate attorney on May 11, 1992. He became in partner in the firm that became known as Zimmer, Duncan and Cole in 1996 and has been a partner in the firm since that time.

Jeff did not run for reelection in 2004.

Jeff has tried to verdict 24 jury trials and has tried hundreds of court trials. Jeff has also briefed and argued 7 reported cases to the South Dakota Supreme Court and 1 reported case to the United States Court of Appeals for the Eighth Circuit, including Ward v.
