Testimonials
“I have been working at NCPA for almost 7 years at the Geothermal Facility in the Geysers in the Mayacamas Mountains that boarders Sonoma County. I have worked with Stratus Engineering Associates during this time and they have helped us get into compliance on some of our projects and are a treat to work with! They are very responsive and knowledgeable! I will be working with them again in the future!”
