What Clients Say

"Your team at PES was instrumental in the successful characterization of materials destined to change the way lightweight/high strength alloys are processed and applied. We could have never met the very aggressive timeline for this research if we had not found such a capable and motivated private partner. You underpromised and over delivered, thoroughly impressing our team every step of the way. Your organizations name is now synonymous with quality, and will be the first choice for all of my projects in need of a collaborative analysis partner. Please let your team know how much we value their dedication and professionalism, they will always be thought of as part of this team, who has been called upon to solve some of the most important material science problems across the U.S. Government."
