ABOUT DERRICK
Let’s be honest: there are plenty of firms that can stamp a set of drawings. But a successful project isn't just about calculations—it’s about the people you’re working with. Today the vast majority of our work comes from clients who have been with us for years and I value those relationships. We've grown together because they know they can pick up the phone and we will figure out the best way forward.
I am the President of EN-TECH Engineering, PA with 24 years of experience in building and industrial system design as well as engineering field support. Design experience includes electrical, HVAC, plumbing, fire alarm systems, solar farm design, process controls and instrumentation.
