Mark Dorsett, a city carrier assistant, was recently delivering mail in a Genoa, IL, neighborhood when he spotted a customer lying on the ground outside a residence.
Dorsett rushed to check on the man, who was unconscious and bleeding.
The Postal Service employee immediately called 911 and comforted the man as he came to.
Emergency responders soon arrived and took the customer to a hospital.
The man, who had severely injured his neck after suffering a seizure that caused him to fall from an upper-floor window, is recovering from the incident.
