Lewisville ISD named new head football coaches for Lewisville and Flower Mound high schools on Monday night.

The LISD school board unanimously approved Katy defensive coordinator Gregg Miller for the Lewisville position, while former Hebron defensive coordinator and current Boerne head coach Dane Johnson was named Flower Mound’s new head coach.

Miller — who’s been an assistant at Katy for more than a decade — succeeds Dick Olin, who was 7-23 in his three seasons at the helm after a successful run at Baytown Lee.

Miller was Katy’s defensive coordinator since 2004, promoted when then-defensive coordinator Gary Joseph moved up to become head coach. Since that time, Katy has added to its rich history, winning 5A Division II titles in 2007 and 2008.

Johnson, a two-sport star in basketball and football for Southlake Carroll, returns to the Dallas-Fort Worth area after three seasons as head coach for 3A Boerne, where he went 14-16.

Prior to the Boerne job, Johnson was a defensive assistant at Hebron, a secondary coach under Joe McBride when Hebron won the Class 4A Division II title in 2005, eventually becoming the defensive coordinator under Brian Brazil.

Johnson replaces Cody Vanderford, who started the football program at Flower Mound. In 12 seasons, Vanderford was 60-64.
