Ring & DuChateau was founded in 1961 by James Ring and Joseph DuChateau, two young engineers with a penchant for quality and a vision for the future.  They based their fledgling firm on a few basic principles that have guided R&D for the past 60 years:

Practice Quality Design

  • Provide a system that suits the project
  • Deliver quality that leaves no question of the intent of the project

Emphasize Service

  • Communication with clients
  • Meet deadlines
  • Stay on budget
