Diagnosed with a lower limb disability at birth, Ronan Tynan had his legs amputated below the knee when he was 20 years old. Eight weeks later, he was climbing the stairs of his college dormitory, and within a year, he was winning races in the Paralympic Games, amassing 18 gold medals and 14 world records. After becoming the first disabled person ever admitted to be National College of Physical Education, he served a short stint in the prosthetics industry and began a new career in medicine. He continued his studies at Trinity College, where he specialized in orthopaedic sports injuries.
