The Kansas Lottery is restructuring its field staff in order to provide better service to lottery players and retailers, and increase sales and transfers to the state. As part of the restructuring, the Lottery will close its Great Bend office. The last day the office is open to the public will be December 13, 2013.“Closing the Great Bend office will allow us to better use our resources,” said Kansas Lottery Interim Director Sherriene Jones-Sontag.
