London-headquartered tech marketing group Next Fifteen Communications Group has moved to acquire a specialist US business.

Next 15 has acquired the US division of Health Unlimited, a global health consultancy and communications agency advancing landmark developments in some of the most complex and challenging areas in health.

Health Unlimited, which includes specialist consultancy Corkery Group, will be rebranded as M Booth Health and operate as a separate agency reporting to M Booth CEO Dale Bornstein. Timothy Bird, global CEO of Health Unlimited and his US-based management team, will continue to lead the agency and its roster of major clients.

“The acquisition is a major milestone for Next 15 as it adds another specialist business to the portfolio and greatly expands our international footprint in the healthcare sector,” said Tim Dyson, CEO of Next 15.

“We see significant complementary opportunities for both businesses.”

Next 15 employs over 1,800 people across 42 offices in 14 countries, incorporating 19 subsidiary agencies spanning digital content, marketing, PR, consumer, technology, marketing software, market research, public affairs and policy communications.

M Booth is known for award-winning integrated marketing programs that engage stakeholders through digital, social, earned media, and experiential channels.

Bornstein said: “Our two agencies share a people-first culture rooted in creating meaningful change through inspired ideas that move people, brands and businesses forward.

“On day one, M Booth Health will boast nearly 50 healthcare professionals expert in everything from pharmaceutical communications and global public health to advocacy and issues management.”

The rebranded M Booth Health is a 25-year-old New York-based global health consultancy and communications agency built by specialists with a legacy of advancing landmark developments in global health and medicine.

Clients include medical device, pharmaceuticals, government agencies, medical societies, advocacy organisations and consumer health.

Bird said: “We believe there are significant synergies between both organisations and these complementary strengths will allow us to shape new offerings for clients in areas such as creative, content, digital, influencer, analytics and public affairs.

“The collaboration allows us to offer our talented teams new opportunities for career growth.”
