What’s your story?

I’m a 7-figure entrepreneur who’s started over 20 companies in my career. I’ve branched out to become an investor, teacher, and highly sought-after speaker for my lessons on entrepreneurship. So far I’ve written three books: 8 Unbreakable Rules for Business Startup Success, The Greatest Entrepreneur in the World, and World’s Greatest Business Plan. And, I host my own podcast.

How did you get into entrepreneurship?

In my mid 20’s, I started a simple auto detailing business called “WaxMaster,” which became a test tube of sorts for my home service businesses. After losing my job unexpectedly, I decided I didn’t want to rely on anyone else for a paycheck so I went all-in on the startup world. 

What values guide you and your work?

Treat people the way you would like to be treated. It’s simple, but it’s an amazing way to build strong connections.
