Andrew Nelson

Engineering Technician - Technical Lead

My background ranges from production welding to outdoor climbing guide but has always had two things in common: Passion and Impact. I want to care about what I do, and I want to make positive, tangible change while doing it.

I have always been a mechanically inclined person, which has been the guiding light of my career. Working at Sigma gives me the opportunity to grow that skillset around an incredibly diverse, highly experienced team.
