Yes, Stipe Miocic still works as a firefighter when he is not fighting inside the UFC octagon.
The current UFC heavyweight champion is a long-running member of the Oakwood and Valley View Fire Departments in his hometown Ohio, where he works as a dedicated firefighter and a paramedic. Over the years, many have cast doubt over his ability to balance the two professions, but Stipe Miocic has proved them all wrong by giving his best to both his careers and not compromising with either.
In fact, Miocic has occasionally participated in fights to raise money for the Firefighter's Foundation and other charities associated with the cause. Stipe Miocic has been a firefighter for over a decade now, starting well before he was even a known name in the world of MMA. He now has a net worth of more than $4 million and makes between $750,000 to a million for every fight he contests in, which means he has absolutely no need for a second job.
