Many of our clients from the early 1980s are still with us today. Thank you!


SHN serves a diverse group of clients, covering the Northern California and Southern Oregon region. We are particularly proud that cities and local governments trust us with their ever-tightening capital improvement budgets.

Approximately one-third of our revenue comes from construction and development companies, a broad category that includes small and large companies, professional (legal and health care) firms, financial institutions, non-profit corporations, the forest products industry, and many others.

SHN’s early success was based in large part on the forest products industry, and today, over 35 years later and with global changes in the industry, many of our original forest products clients are still with us. To the forest products industry, and all clients who have reached out to us over the years, we are deeply appreciative of your long-lasting relationships and trust.
