Sigma Expert Solutions (SES) was founded and created by Demetrius Siachames in 2018 to provide solutions to complex and important engineering challenges. SES was founded on the principles that engineers that care about solving important problems will find a way to solve them.
Demetrius started his engineering career in the United States Navy and a Nuclear Propulsion Officer. He took that experience to the civilian world working for an engineering consulting firm, giving him broad exposure to different fields and opprotunities for varied engineering experience.
It has always been Demetrius’ ambition to create a company based on the reasons he chose to become an engineer when he was seven years old – to better understand the world around him, and leverage that understanding to improve our relationship to the world around us.

SES performs ongoing internal design work as part of its mission to explore and understand a wide variety of topics and industries. Products of this internal work are published as either Design Studies, White Papers, or Inventions. Design Studies are summaries of areas being explored and developing concepts. White papers perform calculations or provide detailed design data for concepts to validate design concepts. Inventions consist of conceptual designs where a patent is being pursued for future business opportunities.
