Here, no one is ever alone.

We started with One case. One patient. One survivor. Today we have touched the lives of thousands and thousands of patients, families, caregivers, supporters, and members of the medical community. CLL is a rare disease with complex treatment options. Treatment options and survival in CLL were once little known about. A profoundly unmet need, this became the inspiration for CLL Society’s daily work of providing expert-informed education and support to the CLL community around the world. And it’s making a huge difference. Why? Because of people like you.

How your donation contributes to the cause. 

We believe every individual living with CLL has the right to access quality care and that knowledge of CLL treatment options creates empowered patients, ready to advocate for receiving their best care. When you donate to CLL Society, you create empowered patients. You are helping CLL patients and their caregivers become equipped with the tools, knowledge, and support necessary to achieve their best possible care. And with CLL Society’s newly launched Research Program, you are also joining the fight to find a cure.
