Fifteen months after making the switch from agent to manager, Paul Haas has left Artists Management Group and rejoined the tenpercentery ranks — this time at Endeavor.

Haas will serve as an agent in Endeavor’s television department. Haas said he made the switch after having an “epiphany.”

“This is not complicated,” he told Daily Variety. “I just realized that I really want to be an agent, and Endeavor has always been a perfect fit.”

Haas joined AMG in February 2000 to oversee the firm’s packaging and television lit department. He had previously spent nine years at ICM, where he headed TV packaging before ankling the agency.

While at AMG, Haas worked closely with fellow ex-ICMer Alan Berger, who heads the firm’s TV interests and coordinates AMG’s relationship with sister TV production house ATG.

“My time at AMG was an incredibly positive experience,” Haas said. “Michael Ovitz is a stand-up guy who was supportive throughout my time there. I’m looking forward to joining my old friends at Endeavor and continuing to work with Michael and AMG in my new role.”

Rob Wolken will now assume Haas’ duties as head of AMG’s TV lit department and report directly to Berger.

Haas’ rep sheet includes “CSI” exec producer Ann Donahue, “The X-Files” exec producer Frank Spotnitz, “Spy Girl” exec producer Becky Hartman-Edwards and “Dark Angel” co-exec producer Rene Echevarria.

It’s unclear at this point which clients will join Haas at Endeavor. But because Haas isn’t jumping to another management firm, it’s possible Haas’ clients could join him at Endeavor while staying on at AMG.

“Paul and I have worked together and been friends for many years, and I look forward to working with him again,” said Endeavor’s Richard Weitz.
