Access Mammoth (formerly Disabled Sports Eastern Sierra) is a 501(c)(3) nonprofit founded in 2003 by Kathy Copeland, headquartered at 1 Minaret Rd in Mammoth Lakes. The organization provides year-round adaptive mountain sports and outdoor recreation programs for individuals with disabilities, veterans, active-duty service members, and others facing barriers to outdoor access. Its Jack & Kathy Copeland Center — formerly the National Wounded Warrior Center — serves as a retreat and conference facility supporting healing, recovery, and reconnection through nature-based programs in the Eastern Sierra.
