The American Orthotic & Prosthetic Association (AOPA) is a national trade association committed to providing high quality, unprecedented business services and products to O&P professionals. Since our founding in 1917, we have worked diligently to establish ourselves as the voice for O&P businesses. Through government relations efforts, AOPA works to raise awareness of the profession and impact policies that affect the future of the O&P industry. AOPA membership consists of more than 1,900 O&P patient care facilities and suppliers that manufacture, distribute, design, fabricate, fit, and supervise the use of orthoses (orthopedic braces) and prostheses (artificial limbs). Membership in AOPA represents a professional milestone; it is recognition of leadership and achievement in the O&P community.
