In 2001 and fresh out of college, Marcus Sheridan stumbled across his first business with two friends and began installing swimming pools out of the back of a beat-up pickup truck. Nine years later, and with the help of incredible innovations through inbound and content marketing, Sheridan’s company overcame the collapse of the housing market and became one of the largest pool installers in the US and currently has the most visited swimming pool web site in the world… River Pools and Spas.
