Omnicom Names Tom Schwenger to Lead Its Health Marketing Branch

By Tom Whitfield

Omnicom appointed Tom Schwenger as chief executive officer of Omnicom Health’s marketing branch last week, giving its combined healthcare agency network a leader with more than 30 years of experience across pharma, biotech and healthcare.

According to Omnicom, Schwenger will manage the group’s global marketing agencies and develop and implement client-engagement models for clients in pharma, biotech and consumer healthcare. His team will include the group’s agency leaders and integrated client leads.

The announcement said the team will continue to leverage Omni and Acxiom, Omnicom’s life science data and AI marketing intelligence platforms, across the enlarged agency network.

“I’m excited to join Omnicom Health at such a pivotal moment, leveraging the scale and capabilities of the newly combined organization to help clients navigate the rapid transformation across the pharma, biotech, and healthcare sectors,” said Schwenger.

Omnicom said Schwenger’s responsibilities span the global agency network, integrated client leads and the shared platforms used to support them. His remit links management of existing agencies with the development and implementation of client work.

What does Schwenger’s role cover?

Schwenger will work alongside Michael Larson, chair of Omnicom Health, while transitioning into the CEO position. Omnicom said the role covers the global marketing agencies within the newly combined healthcare organization.

He succeeds Dana Maiman, who served as Omnicom Health’s CEO for the past year. Schwenger’s remit includes agency management, client-engagement design and the use of shared data and AI tools.

The practical change is straightforward: Schwenger will coordinate the agencies, client leads and shared intelligence tools under one leadership structure.

What experience does Schwenger bring?

Omnicom said Schwenger previously served as president and chief customer officer at Veeva Systems, a cloud-computing company for the life sciences industry. At Veeva, he encouraged early AI adoption and helped triple the organization’s revenue.

The announcement cited that revenue result as part of Schwenger’s more than three decades of experience driving growth and leading strategic initiatives in pharma, biotech and healthcare. His former role also placed him in a customer-facing position at a life sciences cloud software company, Omnicom said.

He added: “This internal evolution, coupled with powerful market dynamics, creates an extraordinary opportunity to drive innovation and growth.”

That background gives the appointment an operating focus on early AI adoption, revenue growth and healthcare client strategy.

How does the Interpublic deal reshape the role?

Omnicom said the appointment follows its acquisition of Interpublic Group (IPG), which formed the world’s largest advertising holding company. Omnicom Health has integrated IPG Health, IPG’s group of healthcare marketing agencies, into its network.

The integration places those agencies under Schwenger’s management alongside Omnicom Health’s existing global marketing agencies. It also connects the enlarged network with the Omni and Acxiom platforms used by agency and client teams.

Omnicom Health was recently named Healthcare Network of the Year at the 2026 MM+M Awards. The company said the recognition further positioned the network as a leading force in healthcare marketing.

Schwenger’s first test will be whether he can turn the enlarged agency network and coordinated client approach into stronger engagement and growth while deploying Omnicom’s data and AI tools.
