Nick Preece founded PMA while studying Electrical Engineering at CU Boulder. With the intention of doing R&D, he helped his customers bring their projects to life. Through this journey, Nick discovered a discipline he fell in love with, transforming an R&D journey into an S-Corp machining company almost exclusively doing machining and inspection for the aerospace and defense industries.
