Omnicom Appoints Tom Schwenger as CEO of Omnicom Health Marketing

Omnicom has appointed Tom Schwenger as Chief Executive Officer of Omnicom Health Marketing, effective immediately. The appointment places an experienced healthcare and technology executive at the helm of the company’s global healthcare marketing agencies as the industry continues to evolve.

Schwenger joins Omnicom from Veeva Systems, where he served as President and Chief Customer Officer. During his tenure, he contributed to business growth, product and service innovation, and the early adoption of artificial intelligence across the life sciences industry. Veeva’s revenue tripled during his time with the company.

He brings more than 35 years of experience in healthcare, pharmaceuticals, biotechnology, and commercial strategy. Before Veeva, Schwenger spent nearly three decades at Accenture, where he eventually led its life sciences practice.

In his new role, Schwenger will oversee Omnicom Health’s global marketing agencies. He will work with agency leaders and integrated client teams to develop client engagement models for pharmaceutical, biotech, and consumer healthcare businesses. The work will draw on Omnicom’s Omni platform and Acxiom’s data capabilities.

Schwenger succeeds Dana Maiman, who is leaving the company. Maiman previously led IPG Health and subsequently Omnicom Health following the integration of the two organizations. Michael Larson will remain Chairman of Omnicom Health and directly oversee its specialty health business.

The leadership change comes as healthcare marketing organizations face growing pressure to connect data, technology, and audience insights with measurable commercial outcomes. Artificial intelligence is also creating new opportunities to improve marketing operations and customer engagement across pharmaceutical and life sciences businesses.
