Who we are:
Welcome to D.O. Smith, we are a product design and development workshop located in Los Angeles California. We have been in business since the first design and development of the first double test plug for plumbers which was made in 1939. Since then we have grown and expanded our services to include Computer numerical controlled (CNC) product development .
We also have our own engineers and machinist with years of experience who have designed and built many products. D.O. Smith is also open to inventors and entrepreneurs who want to take their ideas even further. We can provide assistance with the planning and design of a new product all the way from concept to the final stages of development . We are here to create opportunity, and help both small and large businesses design and develop products for commercial, private, and government institutions.
