Jolly replaces Roger Bumgarner, who announced in March he was retiring after nine seasons.
Jolly will finish out the year at Lake Norman, where he teaches physical education and coaches golf. He will teach P.E. at North Iredell in addition to taking over the girls basketball program.
While coaching Lake Norman, the Wildcats were 156-80 in his nine seasons. During that time, the Wildcats also captured three conference championships and reached 4A state finals twice.
Lake Norman won the 2009-10 4A state championship and Jolly was named the Associated Press North Carolina Coach of the Year.
