About Us

CST Team

We are a US-based core engineering firm, specializing in partial and full turn-key outsourcing solutions. Our business focus is on accelerating product development timelines through innovation, experience, and cost-effective solutions. As a domestic engineering solutions provider, we enable organizations to manage the peaks and valleys of today's competitive business environment.

Founded in March of 2003, we are a privately owned business located in Germantown, MD. Starting with 3 employees, we now have more than 20 engineers. Our business has evolved from its origin as a local North American based outsourcing partner with capabilities to address customers' multi-facetted engineering needs. A progression in business opportunities toward full turnkey solutions guided us to advance our services portfolio to include Hardware and Test Engineering and to expand floor space to accommodate growing prototyping and light production needs. As when we started, our team continues to quickly integrate into any phase of the product development life cycle adding new life to a slow project or to meet special resource and technology needs. Our core business focus is on accelerating product development timelines through innovation, experience and cost effective solutions. As we look forward, we see challenges and growth in new business opportunities with focus on alternative energy solutions and devices used in disaster recovery.
Core Source Technologies is located in Germantown, Maryland. Our facility includes approximately 10,000 square feet, which provides both office and model shop space for prototyping and engineering. In 2009 we added 3,000 square feet to our model shop-prototype space due to demand for quality prototyping, assembly requirements, and pilot production needs. Highlights of this space include a dedicated area with specialized power and AC to meet small and large electronic rack assembly, integration, and test needs. Our shop includes secure, customer dedicated areas for material control.
Through human ingenuity and technology, our mission is to provide world-class engineering solutions, in a timely and cost-effective manner to our clients and their customers.
Our vision is to be the recognized leader in delivering engineering solutions, products and tools to our clients and our partners.
Our most valued resource and our competitive edge. Each is guided by personal values that embrace fairness, honesty, and trust, with a passion for improvement and innovation. As individuals, we take responsibility for our actions; as a collective group, we respect the contributions of others and diligently seek the success of the team.

Our most valued characteristic: steadfast honor and trust. It is not a word or action that you can apply in some situations and not in others. That is why we believe in providing products, services and solutions of unparalleled quality. Integrity is more than just a value — it is our reputation.

Our most valued gift. We recognize that each of us is different and we treat all those with whom we associate with dignity and respect. Our behavior reflects our corporate values, providing a supportive environment that leverages our various perspectives—strengthening us as individuals, as a team, and as a company.
