Thank you for visiting our home page. We've merged with
Short Elliott Hendrickson Inc. (SEH®) -- an employee-owned company comprised of more
than 700 engineers, architects, planners and scientists focused on Building a Better World for All of Us®.
In February, our companies signed a letter of intent to merge and it became official on June 1, 2014. The merger provides us the opportunity to provide a
wider array of services to the clients we serve and more opportunities for those seeking a career in engineering, architecture and planning. SEH and Yaggy
Colby Associates share a common goal to provide the highest quality engineering and architectural design services, and construction administration and management. Our companies also share similar core values, which means that while Yaggy Colby Associates is now part of a larger company, we will continue to deliver an outstanding level of personalized service.
For all our clients, we thank you for the opportunity to serve you over the course of the past 45 years, and we invite you to continue our work together
at our new home with SEH. Learn more about our combined company at www.sehinc.com.
