Our Mission and History
The Hairy Cell Leukemia Foundation (HCLF) is the only nonprofit organization in the United States dedicated to Hairy Cell Leukemia (HCL). The HCLF improves patient outcomes by funding research, advancing knowledge about HCL among hematologists, and providing patients access to educational resources and peer-to-peer support.
In 1985, a group of HCL patients in Illinois formed a support group and established it as a 501c3 nonprofit called the Hairy Cell Leukemia Research Foundation. Twenty years later, a second group of patients wanted to explore strategies to advance HCL research further. They convened leading hematologists and HCL experts worldwide and formed the Hairy Cell Leukemia Research Consortium, emphasizing scientific research. These two groups joined forces, bringing together the core competencies of each organization. Today, the Hairy Cell Leukemia Foundation is well-positioned to continue moving the needle in research and discovery and positively impact patients.
HCLF board members are HCL survivors and advocates and HCLF programs are designed and implemented with patient input. An advisory board composed of hematologists from among the best cancer centers in the world continues to provide clinical expertise for our patient education programs and research initiatives.
