Ortega replaces Matthew Seddon, who left JWT to take the helm of Ace Saatchi & Saatchi six months ago (Media 3 December).
Ortega left BBDO Guerrero Ortega in 2005, and has since been running the brand strategy agency BrandLab.
The move coincides with a name change for BBDO Guerrero Ortega, which has dropped the 'Ortega' from its name.
Agency chairman and chief creative officer David Guerrero, said: "2008 is an important milestone as we will celebrating our tenth anniversary. So it seemed like the right time to update our agency name.
"Jos and I remain good friends and continue to share a common vision of improving the standing of the Philippines in the global advertising industry."
