Siefert Associates, LLC was founded in June of 2000 by Vincent Siefert. At that time he was working out of an extra bedroom in his home and with his dog by his side. Since then, Siefert Associates, LLC has grown from a one-person operation to a team of 35-plus working out of two office locations - Watertown, CT and White Plains NY. Siefert has quickly become the professional engineering firm of choice in the New York City metropolitan area.
We are defined by our Core Values of Honesty, Integrity and Work Life Balance and our network of clients is comprised of peers who share these same values. We are extremely proud of our client relationships, and led by an understanding that our success depends on their success.
Siefert Associates, LLC takes great pride in clearly defining our specialty facet of Civil Engineering. Construction Engineering is the process of determining and designing the most efficient and creative means and methods used to execute large-scale construction projects. The high quality working drawings, supporting calculations, and advanced modeling that we produce are tailored to each project’s schedule and budget, unique site conditions, client’s preferences, and most importantly, safe field operations.
