Protecting Communities, Workers, and Businesses Through Sound Engineering Excellence
In 1990, Marcy Bruce took a leap of faith. She believed in her husband Bob's expertise and their shared vision to build something meaningful together. What started as a partnership between two people with big hearts and a drive to serve has grown into one of the most respected acoustical engineering firms in the industry.
35 years later, CSTI Acoustics stands as a testament to their dedication—not just to the science of acoustics, but to the communities, workers, and businesses they protect. It's been a beautiful journey of growth, impact, and unwavering commitment to excellence.
