Our Team

psn about

Experience in science and engineering

Our core team of scientists and engineers have an average of 20 years’ experience in a variety of disciplines.  Each team member works within one of our three business areas but will frequently work along-side members in one or both of our other two business areas.  This service model has allowed us to save our clients significant time, cost, and troubleshooting efforts that come with using multiple vendors, who are often disconnected from the “big” picture.

When calling PSN, you will talk directly to your project manager and receive accurate feedback about your project and the phase it is in.
