About The Team & Awards

The Commercial One Team, branded in 2016, was originally known as Group One Realty. Group One was founded by top-producing real estate Broker, Pete Vanderham, who successfully helped hundreds of businesses, developers, and investors buy and sell industrial and commercial real estate for almost four decades. Commercial One was developed to represent the team’s philosophy that together in collaboration we can better serve our clients, offer more value, and provide a higher level of responsive service then we can as individuals.
