D & D Machinery & Sales, Inc. was established in 1983 as a distributor and exporter of replacement parts for construction, industrial, and hydraulic equipment.

After incorporating in 1984, D & D (named after owners, David and Dolores Martinez) began to manufacture its own parts and soon specialized in precision manufacturing and fabrication. Three years later, D & D began  manufacturing ground support and aircraft maintenance equipment, vehicular accessories, system components, and other miscellaneous equipment for the US Air Force, Department of Defense and commercial airline customers.

In 1997, D & D became a Blue Ribbon Contractor to the Air Force Logistics Command by successfully completing an order for several TTF90 (C-17) Engine Transport Trailers which involved extensive research and reverse engineering to overcome data deficiencies in design and operation.

The Company later joined The Boeing Company family of Preferred Suppliers as a direct supplier to the C-17 Production Program at Long Beach, California providing ground support equipment and parts.

Classified by the Small Business Administration as a small, woman-owned business, D & D actively supports the efforts of the Administration by serving on the Region IV Board and in an advisory capacity to the National Ombudsman.
