Sosemo Hires Jeanne Jennings to Expand its Media Capabilities

NEW YORK, March 3, 2025 -—Sosemo LLC, an award-winning strategic media planning, buying and campaign management agency that specializes in marketing brands across the digital landscape, announces the hire of media services leader, Jeanne Jennings. Jeanne will be responsible for managing the newly expanded media capability and growing the practice as the Vice President, Group Director of Media. 

With over 20 years of experience, Jeanne joins Sosemo from McCann Health Engagement, an IPG Health Company, where she was a Media Business Leader. Prior to McCann she held leadership roles at CMI, Healix Global, Mediacom and Digitas Health. Jennings has a proven track record of launching and expanding media practices. Her work was recognized with the Xpectives.Health’s Agency Vanguard, MM+M, and The Shorty Awards. She has primarily been focused on healthcare and pharma work, with extensive experience across oncology, rare diseases, women’s health, neurology, and vaccinations. However, at Sosemo, Jeanne will also be responsible for leading media services outside of the health vertical, where she has prior experience in consumer packaged goods, financial services and entertainment.

“Sosemo has been a leader in providing media services across the core channels including search marketing (SEM/SEO) and social media, and programmatic for many years. However, Jeanne will deepen Sosemo’s media expertise by expanding campaigns into more nuanced media, especially within healthcare and pharma. Therefore, we’ll be able to service our clients as an integrated media shop now, rather than limiting our engagements to only the core digital channels. I can’t wait for clients to meet with Jeanne. Her expertise across all media and familiarity with media partners and technologies are unparalleled. Having been in this business for 25 years, there is no one else that I would rather have develop a media recommendation,” CEO Larry Gurreri said. “I’ve been a fan of Jeanne’s for over a decade, having worked with her many moons ago. I don’t think we could have made a better hire.”

“I am honored to join Sosemo as the new Media Business Lead. The agency’s commitment to innovation and data-driven strategies aligns perfectly with my vision for advancing success for our company and our clients. I look forward to collaborating with Larry and the talented team here to drive impactful results and elevate our performance media offerings,” said Jeanne Jennings.

Growth plans for the media capability also include the expansion of creative resources and partners, as well as innovation leveraging AI and predictive & prescriptive analytics.
