Heather's charity work as an Ambassador for the global landmine campaign helped raise over $18.5 million, funding clearance of over 21 million square meters of mine filled land and benefited more than 400,000 people. Her team became the largest funder of landmine clearance in the world funding over 300 minefield clearance and survivor assistance projects. Her efforts and determination in this field took on an ironic significance when in August 1993 her life changed forever when she was involved in a road accident with a police motorcycle and suffered numerous injuries including crushed ribs, a punctured lung, multiple fractures of the pelvis and the loss of her left leg below the knee. Just one year after this accident, Heather arranged for the first convoy of artificial limbs to be sent to Croatia. Since then over 400,000 amputees and survivors of landmine explosions around the world have been helped.
Her personal experience as an amputee and the positive manner in which she dealt with her recovery gives Heather a unique insight and affinity with those who themselves have lived through a tragic experience. Heather voluntarily counsels people from around the world who have lost limbs in accidents, through illness, natural disasters and terrorist atrocities. Her personal advice, determination and commitment help them and their families realize that they can continue to lead rich and fulfilling lives despite their injuries. It was in this spirit that Heather appeared on the hit US television show Dancing with the Stars in 2006, proving this point in spectacular cart-wheeling style.
