BBDO's Andrew Robertson Takes Over Omnicom Advertising as Troy Ruhanen Retires
Omnicom has named BBDO chairman Andrew Robertson CEO of its combined Omnicom Advertising division, effective immediately, as founding chief Troy Ruhanen retires after two decades.
The leadership change
Omnicom has appointed Andrew Robertson, chairman of BBDO Worldwide, as CEO of Omnicom Advertising, effective immediately. He succeeds Troy Ruhanen, who is retiring as president and CEO of the division after more than 20 years at the group, including a spell running TBWA\Worldwide. Robertson joined BBDO in 1995 and has led it for much of his career.
Omnicom Advertising unifies the creative networks of BBDO, DDB, TBWA and the Advertising Collective — a structure formed in late 2025. Ruhanen said he and Omnicom CEO John Wren had planned his exit "for some time" but extended the timeline after the IPG acquisition and the division's formation. Wren credited Ruhanen with "bringing together our combined organization."
Why the timing matters
Read between the lines and this is a signal that Omnicom considers its IPG integration largely done — stable enough to hand a founding leader's role to a proven operator and shift the emphasis from merging to growing. You don't change the driver mid-crisis; you change when you want to accelerate.
Our read: for the biggest holding company on earth after the IPG deal, the message to clients is that the plumbing is built and now it is time to sell. Robertson's BBDO pedigree — a creative-network leader, not a finance or operations figure — hints at where Omnicom wants the next phase of the story told.
What clients and talent should do
If you are a client inside BBDO, DDB or TBWA, press for clarity now on what "one creative organisation" means for your specific service team, staffing and pitch approach. Leadership transitions are exactly when accountabilities blur; get yours renewed in writing.
If you are in an active review, use the moment as leverage: ask Omnicom directly how the new structure changes who works on your business and how creative and media integrate post-IPG. And for agency talent, expect a period of role clarification — the reorganisation that follows a merger is usually where careers are quietly reshaped.
