Steve Hightower's first job was working nights and weekends for his parents' cleaning business.
While he was in college, it made sense to continue.
"I started as a janitor. I started cleaning floors and toilets and doing those things that most people would never even dream of doing," says Hightower. But, he says, "I wanted more."
When he graduated from Wright State University in Dayton, Ohio, in 1978, he started his own small construction company.
As he tried to grow his business, Hightower struggled to get access to credit. At the same time, he learned about a program to sell gas in Ohio. That gave him ideas.
Hightower has always had big dreams, and he has never doubted his capability.
"When people ask me would I ever have imagined I would be where I am today? Absolutely,".
"Because if you don't think that you can be great, you'll never be great. And I knew that I was gonna be great a long, long time ago."
