DS Ragsdale has 15 years experience as Vice President, Operations and Quality Control for the largest manufacturing operation using our process west of the Mississippi.  His 300,000 square foot plant was originally a Mattel Toy plant before most their manufacturing moved offshore but now has an in-house tooling design center as well as extensive manufacturing and warehousing capacity.  The company occupies one of the largest manufacturing buildings in Ontario, California...  a train spur runs into the plant.  DS has comprehensive composite manufacturing and estimating experience.  At the company producing US Enclosure products, DS became VP Operations because he had both a fundamental and detailed, precise knowledge of the requirements needed to take a potential job from concept or engineering drawing to completion starting supervising that the tooling was properly made, client proofs were approved, all manufacturing materials were available then correctly blended and mixed, then correctly manufactured to client specifications and tolerances then properly warehoused and shipped with real time inventory reports.

DS's impact to US Enclosure cannot be underestimated in regards to his experience to obtain exactly our clients’ needs and requirements.   Before his tenure with our subcontractor, Devin was employed as an Engineer at Western Digital (Hard Drive).  He also has been involved with Engineering Contract-Project Management for companies like Disneyland, Burger King, and the Electrical Utility named Western Montana.
