The firm history dates back 60 years to a small civil engineering and land surveying firm on Long Island.  In 2010 Christine Gayron, LS and Jason Graf, LS joined Greg de Bruin, LS as principals of the firm.  Greg retired in 2020 and Christine and Jason remain concentrated on our core competency -- geomatics. 

GdB grew from 9 people in 2010 to more than 100 today across 3 offices. The focus remains on answering one question for our clients --  where?   Knowing the 3D position of physical features, the extent of underground utilities, and the location of property boundaries serves as the indispensable foundation for design, construction, and real estate transactions. 

Precision is nothing without Accuracy and both depend on what's needed and when.

Balancing speed, quality, and price is where experience counts most and where our staff shines.  Count on GdB to collaborate with your team and develop a solution that works for your project.
