About ASH

The mission of the American Society of Hematology (ASH) is to foster high-quality, equitable care, transformative research, and innovative education to improve the lives of patients with blood and bone marrow disorders.

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.

Perspectives encompass the breadth of hematology and medical oncology, showcasing adult, pediatric, classical, malignant, research-oriented, and clinical perspectives—all shared through the lens of a diverse, global community.
