Travel Leaders Group has a new CEO after the sudden resignation of Ninan Chacko.
Chacko is leaving to pursue other opportunities, TLG said.
His replacement is current president J.D. O’Hara who now adds the CEO role to his duties.
O’Hara was with Travel Leaders until 2014 when he became president of Tzell Travel Group, and returned to the company as president a year ago.
O’Hara has worked closely with Chacko over the past year.
Since rejoining the group he has overseen all group operations, such as mergers and acquisitions and strategic planning.
"I am extremely excited about the tremendous opportunity to lead such a team of professionals. This company has grown to become an industry powerhouse over the last decade," O’Hara said.
