More than 30 years later, the same person still answers the phone.
Rainer Herbert Keller has been a shareholder of MCO Communication since 1996 and has carried the primary responsibility for the agency since 2000. Based in Monaco since 1987, he brings nearly four decades of experience in financial consulting, mental training, communication, strategic networking, and the development of major international events.
His name appears only rarely in interviews, credits, or press reports — by conscious choice. His credo remains unchanged to this day: life is easier behind the camera.

Those who know Rainer personally are aware that his cabinet still contains numerous all-access passes and memorabilia from decades of international projects.
Among the personalities he has met throughout his professional career are Michael Jackson, Audrey Hepburn, Princess Diana, the Dalai Lama, Nelson Mandela, Tina Turner, Gianni Versace, Karl Lagerfeld, Paco Rabanne, Bill Clinton, Barack Obama, and many others — always in connection with his respective role, responsibilities, and expertise.
For more than four decades soon, the reputation of the house has been built where discretion matters more than visibility.
Even in 2026, Rainer continues to conceive and realize projects, events, and brand experiences. In addition, he advises companies on team development, sustainable sponsorship engagement, and the authentic integration of brands into relevant environments.
Small enough to remain personal. Experienced enough to operate at the highest level. And close enough to people to build, develop, and maintain relationships over decades.
