L3 Foundation

L3 Foundation (EIN 46-5510008) is a Texas-based 501(c)(3) public charity founded to honor the memory and final wishes of Landon Ahrendt. The organization focuses on funding pediatric cancer research—particularly for soft-tissue cancers such as rhabdomyosarcoma—and on helping families navigate the financial and practical burdens of a childhood cancer diagnosis. Since its founding in the mid-2010s the foundation has been an active grantmaker and donor partner with hospitals, research centers, and family-support programs (for example, supporting Camp Bring It On and partnering with health-system foundations to sponsor research initiatives).
