FOUNDATIONS

In 1969 Lee Trentman moved his wife and three children from San Diego to Northern California.  With a vendor's product catalog and some business cards in hand, Lee hit the road to call on new customers. Interstate Sales was born. He missed the people and market place of San Diego, so 43 years later, he helped establish T-Man Traffic Supply in 2012.  Lee knew that there were many other competitors in the market place, but he trusted that building personal relationships through trust, honesty, and reliability would set him apart from the rest of the pack.  Lee modeled that mindset until his passing in 2017, and taught his family and  employees to treat others the way you want to be treated. Today we honor our founder by continuing his legacy of fair pricing, un-paralleled service, and building  trust in our ability to do what we say we will do.
