When Mary Evelynn Warren celebrates the anniversary of her liver transplant each June, she is reminded that she is living a life many doctors in 1984 never expected would be possible.

Now a Big Spring resident, Warren received a liver transplant on June 17, 1984, when she was just 41/2 years old.

At the time, liver transplantation was still considered highly experimental, survival rates were far lower than they are today, and securing funding for the procedure was often one of the biggest obstacles families faced.
