Who We Are

With more than 18,000 members from nearly 100 countries, ASH is the world's largest professional society serving both clinicians and scientists around the world who are working to conquer blood diseases.

History of ASH

In April 1958, the first official meeting of the American Society of Hematology was held in Atlantic City, New Jersey, where more than 300 hematologists gathered to discuss clinical and research matters related to blood and blood diseases. Since that initial meeting, ASH has played an active and important role in the development of hematology as a discipline.
