Underwood said, "We are getting one of the most outstanding high school basketball coaches in the South and we are looking forward to his arrival."
Ladner is a graduate of Oak Grove High School where he was a standout baseball and basketball player.
St. Stanislaus Athletic Director Stacy McRaney told WLOX that he was not aware of the hiring. He's attending a coaches clinic in Jackson.
McRaney said, "If Ladner is leaving I believe St. Stanisalus will be able to hire a very good basketball coach."
He also said Ladner was an outstanding coach who provided leadership and a winning attitude for the students at St. Stanislaus. He guided the Rockachaws to the Class 4A State Championship title this past season.
The 2010-2011 Rockachaws posted a 34-2 record en route to the championship and had a winning streak of 29 consecutive games. Both were school records.
Ladner was named the Mississippi Association of Coaches 2011 Boys Basketball Coach of the Year.
He is a super coach but even a better person. Oak Grove High School is gaining someone special, a coach who will turn the Warriors into a basketball power.
Ladner replaces Ed Bradley who left Oak Grove High School to become head basketball coach at Long Beach High School.
