ASH is returning to San Diego for the 66th ASH Annual Meeting and Exposition from December 7-10, 2024.

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.

Mission: Fostering high-quality, equitable care, transformative research, and innovative education to improve the lives of patients with blood and bone marrow disorders.

In April 1958, the first official meeting of the American Society of Hematology (ASH) 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.

For more than six decades, ASH has sponsored its annual meeting, the premier education and scientific event in the field of hematology, and has published the journal Blood, the most cited peer-reviewed publication in the field.
