Robert D. Friedman is most well-known for being the co-founder of Auction.com, one of the largest real estate auction firms in the United States.   Rob is definitely one of those guys that learned more by doing than by studying in a classroom. He started an auto repair shop at the age of 19 making $100k/year, and then he used that as a springboard to start many other business ventures, mostly in the real estate industry.    He has been working with his business partner, Jeffrey Frieden, for over 40 years. And together, they have participated in thousands of real estate transactions, grossing billions in sales.   Rob is also involved in various charitable organizations. One of his proudest achievements is starting a school in Nicaragua called veraschool.org that educates bright, young girls in underserved communities. Go check that out to see how you can help.
