CLL Society is an inclusive, patient-centric, physician-curated 501c3 nonprofit organization whose mission is to address the unmet needs of the chronic lymphocytic leukemia and small lymphocytic lymphoma (CLL/SLL) community through patient education, advocacy, support, and research.

In 2005, when Dr. Brian Koffman was diagnosed with CLL, he and his wife, Patty, sought to define and acquire the best possible care for one CLL patient: Brian. Uncovering critical, unmet needs within the CLL community, they created the nonprofit CLL Society in 2013 to function as a conduit, making vital support and credible, cutting-edge treatment information available to all CLL patients and their caregivers. Today, CLL Society serves tens of thousands of CLL patients and their families and caregivers, as well as the CLL medical community around the world.
