Client Testimonials

Pete Secor, President of Evergreen Telemetry:


The professionals at Proof Engineering deliver excellent service and support.  They are proficient and prompt when designing and fabricating in both plastic and metals.  The engineers at Proof take the time to discuss project goals in depth so they can offer the best all-around solution.  Because they operate as if they are an extension of in-house engineering at my small company, I'm giving them an increasing share of our design work.
