Peterson Sullivan is proud to announce the launch of its new website!  The site is now live and you are invited to explore its offerings at

The goal of the site was to provide visitors with a more user friendly experience including improved navigation, easier access to service information and relevant content, plus responsive capabilities to improve the mobile viewing experience.  There is better integration with social media platforms to share information on career opportunities, latest announcements, and thought leadership articles from industry and service experts.

The web design refresh better showcases the culture of the firm and is a more accurate representation of Peterson Sullivan’s position in the market.  The vision, concept, and design for the new site was a collaborative effort between the firm’s website committee and Drake Cooper – a Northwest-based full-service advertising agency in Boise and Seattle with creative, digital, media buying, SEM, content marketing, design and production services.

For questions or feedback regarding the new site, please email Kassidy Vietti, Marketing Communications Strategy Specialist at
