Arora will report to Elvis Dias, managing director and Jitendra Khokle, COO at AMO.
On Arora's appointment, Dias said, "Manish is probably one of the few classic client servicing guys in the industry, who can handle very high pressure and has got a great record with clients. He is aggressive and an all rounder by his own right."
Apart from Saints & Warriors, Arora has previously worked with The Classic Advertising (Dubai), Quadrant Communications and O&M for clients such as Pantaloons, Staples, Amul Innerwears, Elf Lubricants, Toshiba, Alcatel Videocon, Voltas and Sansui, among others.
