Reveille has named Eden Gaha as its president, effective in June.

Appointment follows the announcement that managing director Howard T. Owens will be leaving the company next month. Gaha, who has been showrunner of “Celebrity Apprentice” since 2006, will lead Shine-owned Reveille’s unscripted, creative, development, digital and brand integration departments.

Gaha will report to Shine Group Americas CEO Emiliano Calemzuk, who oversees the company’s scripted output.

“I am very fortunate to have been given this opportunity to guide an already successful company through the next phase of its continued growth,” Gaha said. “The media landscape continues to evolve, and new media increases the demand for entertaining and innovative content. As such, I am thrilled to work with both the creative, forward-thinking and multi-platform teams both at Reveille and in the Shine Group companies around the world.”

A native of Australia, Gaha began working in the U.S. as a supervising producer on “Survivor” in 2003, then later served as co-executive producer on other Mark Burnett productions including “The Contender” and “Rock Star.”

Gaha joins other recent additions to Reveille including Heather Schuster as senior veep of creative affairs, Matt O’Brien as VP of creative affairs, David Anderson as head of digital and David Benavente as senior production finance and administration veep.

“Eden’s proven creative and showrunning expertise with major network unscripted productions makes him a perfect fit to lead Reveille,” Calemzuk said, “His appointment, along with the recent additions to the team, will further develop Reveille’s reputation. … In addition, boosting our already successful digital capabilities significantly will enable us to embark confidently on the next stage in the company’s evolution.”

Reveille’s existing projects include NBC’s “The Office” and “The Biggest Loser,” Fox’s “Master Chef,” Bravo’s “Tabatha’s Salon Takeover” and Lifetime’s “One Born Every Minute.”
