Why March 27TH?
This is the official date the MSL Society became a 501(c)(3) nonprofit organization. International MSL day has been officially registered through National Day Calendar®.
Why Now?
Since being first established by Upjohn Pharmaceuticals in 1967, MSLs have become increasingly more important to the success of the companies that employ them. As a result, the MSL profession has grown exponentially over the last several years, and according to a recent global MSL Society survey, 68% of managers had planned to expand the size of their MSL teams within the next two years. Today the MSL role is more important than ever to the success of the companies that employ them. Having an official day dedicated to MSLs is a unique way to recognize the profession, and raise awareness of the importance of the global MSL profession.

International MSL Day occurs every year on March 27th!
