Great Bend USD 428 has filled a position for an assistant principal at Great Bend High School next year but now has two openings for elementary school principals. During a luncheon meeting Wednesday, the board approved the retirement of Park Elementary School Principal Phil Heeke and appointed Kip Wilson, current principal of Jefferson Elementary School, to the administrative opening at GBHS. Assistant GBHS Principal Randy Wetzel announced his retirement earlier this year and it was approved at the March school board meeting.
