Our Story
Howard chose Pinnacle as our name when he and I were looking at the peak of Denali while on a trip to Alaska for a right of way conference; the name represents what he wanted us to be, a company whose reputation for standard of service to clients and the affected public is at the highest level. Howard, Jennifer, and I knew that in order to accomplish his goal, it would require a diverse group of professionals and a culture that acknowledges their value by offering continuous employment, great benefits, and equal opportunities for all. Today, Marcus and Aaron are my partners at the helm, sharing the original vision but full of new and exciting ideas.
The details of our story are vast and varied. The below gallery of decades, is much like Pinnacle's "yearbook" that includes some notable projects, highlights of our company culture, and a glimpse into the variety of clients we have served throughout the years.
