Speaking to ABC News Isiah said his heart was "beating so fast" after seeing the fire in the mobile home at the back of the Lake John's Motel in Oakland and he knew he had to help.
"I had to go in there with the fire to grab the kids while the dad kept running in there with water trying to put [the fire] out," Isiah told reporters.
After emerging from the blaze with the two kids, the brave youngster called the Orange County fire department. Fire officers then arrived to rescue two more children from the fire.
It has been claimed the fire started from the stove in the mobile home, but the Orange County fire marshal has said further investigation is required into the fire.
As for the brilliant Isiah, he hopes to be a fireman when he grows up.
"I've been wanting to [be a fireman] ever since I was five years old. Even though I have to go through all this hard work, I still want to be one," said Isiah.
We think he will make a brilliant fireman.
