About Us

In the year of America’s 200th birthday, 1976, we opened our doors determined to serve our clients with a fresh, new approach to architecture and engineering – ignoring traditional boundaries and bringing all essential disciplines together with a carefully assembled team of knowledgeable and dedicated professionals. We have grown from our three founders to a team of 70 members who share a deep appreciation for hard work, efficiency and creativity. As an organization, we remain fundamentally lean, learning from over 45 years of doing business and maintaining our strength throughout a variety of economic environments and helping our clients do the same.
