"I started running through the hospital because someone was like, 'We need help with CPR," recalled clinic worker Christy Mittler.
Luckily, her colleague Bill Wilson and bystander Corey Hart performed CPR until they could feel a pulse.
Correa wants everyone to know that Wilson and Hart performing CPR saved his life.
"I see that CPR is the reason I'm here," said Correa. "I want to learn, so just in case it ever happens, I can save someone else's life."
Deputies said Correa was walking his three dogs when it happened. The dogs ran away after the strike, but deputies found them after searching a nearby wooded area.
A gaping hole in concrete was left where the lightning bolt struck the man.
Friends and family have created a GoFundMe account to pay for Correa's hospital bills and recovery. You can make a donation here.
