Sam Simon

Chairman, Simon Holdings and its affiliates

Simon started in the fuel business in 1976, while working at one of his father's 30 gas stations. In 1980, he assumed management of all 30 stations as well as an ice company. Simon ran the businesses until 1985 when he purchased his first fuel truck using a $30,000 credit card cash advance. With this truck, he was able to provide wholesale delivery of gasoline and diesel fuel to his customers on a 24-hour basis. Thus, Atlas Oil Company was born.

Today, Atlas Oil Company is one of the largest national fuel distributors in the country. Atlas delivers nearly 1 billion gallons of fuel per year. Approximately 2 billion gallons are under long-term contracts. Atlas Oil Company's customer base ranges from commercial and industrial fuel users to hundreds of retail locations under the Marathon, Clark, CITGO, Phillips 66, and Valero brands across an expansive geography.

Simon was appointed to the National Petroleum Council by Secretary of Energy Spencer Abraham and is on the advisory board. In 1999, he received the Ernst & Young "Entrepreneur of the Year" award. He currently serves as a regional and national judge for the Ernst & Young "Entrepreneur of the Year" program.

As Chairman for Simon Holdings, Sam Simon has built a strong foundation and a culture that characterizes his passion for winning.
