The Orthotic & Prosthetic Activities Foundation (OPAF) is a nonprofit organization, a 501c3 public charity, established and incorporated in January 1995 by the former Orthotics and Prosthetics National Office. The Orthotics and Prosthetics National Office is now three separate organizations including The American Orthotic and Prosthetic Association (AOPA), The American Academy of Orthotists and Prosthetists (AAOP) and The American Board for Certification in Orthotics, Prosthetics and Pedorthics (ABC). Each of these organizations still supports OPAF through both financial and in-kind support.
OPAF was initially dedicated to providing financial and in-kind support to the 1996 Paralympics. OPAF now generates its own initiatives through partnerships with individuals, organizations, and institutions engaged in improving the quality of life for those with physical and mobility challenges and raising public awareness of physical disability and limb loss.
