In 1975, Salas O’Brien established certain fundamentals that provide the foundation for our firm today. Because of these fundamentals you will come to expect a difference in every aspect of your project.

  • Each project will be Principal led with proactive and personal service. Each project will be tailor-made to the site and unique client needs; there will be no cookie-cutter designs here.
  • We are hyper focused on the quality of our work and delivery. You will see fewer change orders, improved schedule, and savings on life-cycle utilities—all of which will give you complete confidence in our delivery.
  • We will only act with your best interest in mind with no conflict of interest. We will never represent or sell any specific equipment or system manufacturing company. We will advise which system is best for you, given the situation.
  • We will take care of the team and do the right thing, always.

Relationships are everything to us!
