Mediassociates Elevates Key Executives

Mediassociates has promoted three executives into newly created roles to lead its expanded client portfolio, as the agency has doubled billings in the past year by adding such clients as Fannie Mae, Ziply Fiber, Strava, Rochester Regional Health, and MIDFLORIDA Credit Union. To keep pace, the agency has grown from 60 to 100 employees. 

“We’re expanding our leadership to ensure we keep clients ahead of the relentless change in media,” said Jeff Larson, president of Mediassociates. “As our approach to developing Precision Branding programs around new data signals delivers for more clients, we need senior-level leaders who are interdependent and dedicated to our pillars of full-funnel, predictive modeling, media attribution and analytics.”  

· Jesse Rosenschein takes on the new position of senior vice president, head of integrated investment, responsible for all client investment decisions across digital, traditional, mobile, and emerging media. Since joining Mediassociates in 2017, Rosenschein has dramatically expanded the agency’s digital practice by applying client data and strategy across an increasing array of media channels to yield measurable gains in advertising performance. Rosenschein’s practical approach to high-level strategy inspires a real-time, real-world focus that leads the digital team to continuously deliver bigger brand results more efficiently.

· Mark Mirsky assumes the new position of senior vice president, head of account strategy, and will oversee all the agency’s media planning functions and teams across its portfolio of clients. Mirsky joined Mediassociates in 2020 following a long tenure at OMD. His deep client empathy and holistic planning approach has expanded the agency’s largest accounts by delivering higher performance and world-class service. He will lead the planning teams in deploying Mediassociates’ advanced tech stack to create precision branding programs.

· Jim Santa Barbara becomes executive director, insights and analytics, responsible for all data insights, measurement, reporting, and modeling at the agency. Since joining Mediassociates a year ago, Santa Barbara has advanced business forecasting for clients by unearthing implications and opportunities hidden in first-, second- and third-party data. He will lead the agency’s in-house analytics team in building new integrated measurement systems.

“We pride ourselves on delivering better thinking for our clients,” said Larson. “Our new leadership structure will do that, and clients will see the effect in their business results.”
