For Over 70 Years...

Dayton T. Brown, Inc. (DTB) has been synonymous with the pursuit of excellence and customer service for over 70 years. As a leader in the fields of testing, engineering, logistics, technical publications, and military mission systems, DTB has gained national respect and recognition. The Company was founded in 1950 and is headquartered on 32 acres in Bohemia, NY.

DTB began operations in a plant of approximately 16,000 sq. ft. in Copiague, NY. Founded by Dayton T. Brown, Sr. as a manufacturing sheet metal operation, the Company expanded into testing in 1952 and technical services in 1966. As the Company grew, DTB purchased land in nearby Bohemia, NY and moved the operations to this location in two major stages in the 1960s. The Company has remained a privately held corporation since its beginning.
