Caleb Garuba, from Newham, initially aspired to become a cardiothoracic surgeon until he witnessed the tragic incident.
It caused him to change the direction of his life.
He has shared his story to mark International Paramedics Day and urged Londoners to consider a career at the London Ambulance Service.
Caleb said: “Everything changed on a fateful day while I was at my aunt’s shop.
“I heard a frantic shout from outside. Alarmed, I rushed outside to see what had happened, and my heart sank as I realised that a motorbike had struck a child.
“The chaos that ensued was overwhelming, with people rushing to help the boy, who was lying motionless on the ground.
“I later learned that he died on his way to hospital.
“This traumatic experience profoundly impacted me.
“In that moment, I realised the vital role that immediate care plays in traumatic situations.”
Caleb joined the London Ambulance Service 12 years after the tragic incident, having served as a paramedic in Nigeria for seven years.
While the incident drove him to become a paramedic, he has experienced several uplifting moments where he positively impacted patients and the wider community.
Caleb said: “About a year ago, I responded to a call about a cardiac arrest.
“The situation was critical, and we worked tirelessly to revive the patient.
“After what felt like an eternity, we managed to stabilise him, and he eventually spent days in the hospital recovering.
“Knowing that he not only survived but is now thriving is an indescribable feeling.
“The highlight came when he reached out to express his gratitude and requested to meet the team that played a part in saving his life.
“That moment was truly priceless.
“It was an incredible reminder of why I do this work—being able to help people during their most vulnerable moments is something I cherish deeply, and I never take it for granted.
“It brings a deep sense of satisfaction and purpose to my own life.”
Launched in 2022, International Paramedics Day takes place on July 8 each year, marking the anniversary of the birth of Dominique-Jean Larrey, often referred to as the father of modern-day ambulance services.
