CLL Society Inc. is a patient-centric, physician-curated, non-profit organization dedicated to addressing the unmet needs of the Chronic Lymphocytic Leukemia (CLL) and Small Lymphocytic Lymphoma (SLL) community. They focus on providing comprehensive patient education, fostering robust support networks, leading advocacy efforts, and funding critical research to improve treatments and ultimately find a cure for these conditions. Their resources are designed to empower patients, caregivers, and healthcare professionals with accurate, up-to-date information and a supportive community.
Serves as the central administrative hub for coordinating patient education programs, support group networks, advocacy initiatives, research funding, and the dissemination of medical information related to CLL and SLL.
As a non-profit prioritizing resource allocation towards its mission, the 'headquarters' is an administrative center rather than a large, architecturally notable facility. The focus is on functionality and accessibility for operational needs.
A mission-driven, compassionate, and collaborative environment. Staff and volunteers are deeply committed to patient advocacy, scientific accuracy, and empowering the CLL/SLL community through support and education.
The headquarters acts as the official point of contact and coordination for a leading national organization providing vital support, education, and resources for individuals affected by CLL/SLL, their families, and healthcare providers.
While primarily focused on serving the community within the United States, CLL Society's extensive online resources, including educational materials, webinars, and articles, are accessible to CLL patients, caregivers, and healthcare professionals globally. They actively engage with international experts and may collaborate with similar organizations worldwide to share knowledge and contribute to the global understanding and management of Chronic Lymphocytic Leukemia.
