Tim Letts, a former US army veteran who now works as an Uber driver, unknowingly had his life changed when he picked up Bill Sumiel from his dialysis centre.

During the ride, Bill shared with Tim his need for a kidney transplant due to kidney failure caused by diabetes that he had been dealing with for the past 20 to 30 years.

Despite being advised by doctors to actively search for a donor, Bill had been waiting on the donor list for three and a half years.

Moved by Bill’s story, Tim offered to donate one of his kidneys by the end of the journey.

After undergoing tests, Tim was found to be an excellent match for Bill, and the transplant was successful. Bill expressed his gratitude to Tim, referring to him as an angel who came out of nowhere, and he was no longer required to undergo dialysis or wake up at 3 a.m. to start his day.
