CMN is led by Thomas Poisson, Fabrice Gutman, and Jean-Marc Esnault.

With a long presence in the Paris region, CMN is the leading private-sector entity dedicated to nuclear medicine and provides specialized diagnosis (e.g. cardiology, oncology, and inflammatory diseases).

Since its inception, the group has grown both by opening new locations and through external growth. CMN currently operates six centers, and its flagship location is in the center of Paris (Hôpital Privé des Peupliers). CMN aims to strengthen its leading position and give all patients access to quality diagnosis.
