The late Paul Duttenhaver founded Interserv in 1983 in Houston, Texas, where it has operated ever since.  Over the decades that followed, Mr. Duttenhaver and now-retired General Manager Mark Leonhart grew the company into an important global supplier of industrial supplies.  At present, Paul’s nephew, David Beutel is leading Interserv into the future on the foundations Mr. Duttenhaver established for the company: reliability, quality, and customer service.

Today Interserv makes daily shipments of quality piping products to refineries, fabricators, construction and engineering firms, and regional distributors in Mexico, Colombia, Venezuela, Chile, Singapore, Thailand, and Malaysia!
