After spotting a tornado in the sky, he guided eight people into the bank's vault and locked it.
"It only locks from the outside and you can't lock it from the inside," Willers told reporters. "And it had to be locked, otherwise the tornado would suck the door open."
After locking them safely in the vault, he took cover in the basement, just minutes before the tornado hit.
"I was prepared to die," Willers said. "I thought I was going to die. We're like a family, you know, I'm the president and I take care of my family."
After they believed it was all clear, he opened the vault and everyone came out. But, a short time later, they spotted another tornado, and Willers again locked them in the vault. He headed back to the basement. About five minutes later, everyone was able to safely come out.
