Welcome To Keystone

Thank you for visiting our website. This site was designed to give you a brief introduction to our firm and a few of the projects we have been proud to be a part of. Strategic growth is the key to the success and vitality of our firm. We have grown steadily over the last twenty years through mergers and acquisitions along with the addition of services. Our most recent merger with Hawk Engineering has significantly broadened the professional services we offer to clients. We provide services in the disciplines of architecture; mechanical, electrical, civil, geotechnical, environmental and structural engineering; interior design and survey. With our staff of over thirty members, we have provided professional services throughout New York and Pennsylvania from our main office in Binghamton, New York, and two satellite offices in eastern New York and northern Pennsylvania. We are proud of our reputation for providing quality professional services on time and within the budget constraints of our clients.
