Owner and primary engineer Doug Pientak brings 30+ years of experience spanning electrical, PLC, and mechanical engineering, plus a rare foundation in core programming languages like Assembly and C. That range lets him see every project from every angle—and it's the same versatility he's nurtured throughout our team. What started as one engineer's passion in a small machine shop has grown into a multimillion-dollar company with a team of 20+ talented people, but our philosophy hasn't changed.
Everything we build is designed and manufactured right here in the USA. We take pride in engineering solutions that aren't just functional, but elegant—clean, efficient, and built to last.
"If it's worth doing, it's worth doing right! "-Doug
