Pam Nicholson, CEO of Enterprise Holdings, has nearly doubled the company's revenue and size since becoming CEO, according to an article by Investor's Business Daily. 

Pam Nicholson started at Enterprise as a manager trainee in 1981 and learned the business from the ground up, the article reported. Nicholson grew the Southern California market from a 1,000-unit fleet and doubled profitability in the New York region. She returned permanently to her native St. Louis in 1999 as senior VP of North American operations and was appointed chief operating officer in 2003.

Andy Taylor, former CEO and son of founder Jack Taylor, recommended Nicholson for the CEO position in 2013. 

At the time, Enterprise had just launched its first European franchise. One of Nicholson's main goals was international expansion and the company now has offices in more than 90 countries and territories. 

Since becoming CEO, Enterprise Holding's revenue has increased from $16.4 billion in 2013 to $22.3 billion in 2017 (per fiscal year).
