GCI Health Germany marks its 25th anniversary this week — a signature milestone that underscores our commitment to delivering exceptional healthcare communications to clients and communities around the world. Founded by Horst Muether as part of Grey Europe in 2001 and formally integrated into WPP in 2019, GCI Health Germany has grown into a vital global agency. Today, Horst and Katharina Tolkmitt, who has also been with agency since 2001, brilliantly lead our Hamburg and Düsseldorf teams as General Managers.
Over the past 25 years, GCI Health Germany has established an impressive track record of success, partnering with top-tier pharmaceutical clients across a diverse range of therapeutic areas. The team’s deep market-level healthcare expertise, combined with scientific and medical communications acumen, allows them to excel in scientific storytelling and medical education. Their comprehensive approach encompasses multichannel strategies that effectively raise awareness and spark crucial dialogue within the medical community and broader public — from the latest research in HIV to pressing topics in asthma, COPD therapy and chronic sleep disorders.
Central to GCI Health Germany’s enduring success is its team-centric culture, characterized by long-tenured colleagues, open communication, robust career support and a positive team spirit. This collaborative environment fuels consistency and reliability that clients value, fostering long-term partnerships and business stability.
“By continually empowering their teams, Horst and Katharina have built an agency that sets a high benchmark for global excellence,” says Kristin Cahill, Global CEO of GCI Group. “The GCI Germany team’s passion and dedication over these last 25 years have profoundly impacted health in Germany and beyond.”
