Our Story

While there has been a world of change over the past century, a lot of things are not so different after all. Something extraordinary was brewing in 1910. A brilliant young entrepreneur and pioneer oilman by the name of Henry L. Doherty had a vision of creating exceptional business opportunities inspired by progressive ideas of improving the lives of everyday people. On September 2, 1910, Doherty founded the Cities Service Company.
