Mission & purpose

For over 50 years, PSI has provided technology solutions and innovative products to our government and commercial customers. Our employee-owners continue to grow the company across a range of markets applying emerging science to important problems. We play an important role in the development and transition of advanced technology from the laboratory to commercial and government use. PSI has a highly interdisciplinary staff with advanced degrees in chemistry, biology, physics and applied physics, electrical, aeronautical, and mechanical engineering, and materials science. We are structured to enable cross-disciplinary collaboration between our scientists and engineers in order to develop solutions to our customers’ technical problems. Our extensive laboratory and prototyping facilities as well as low rate production capability enable us to rapidly go from concept to advanced prototype, and then on to manufacturing. We couple this internal capability with our long heritage in field and clinical testing of prototype systems enabling us to gain valuable feedback leading to rapid improvement.
