Company announcement

CSI concluded our work on current projects on December 31, 2025.

We have greatly valued the opportunity to serve our clients and partners over the years and we are committed to a smooth and responsible cessation of services.

Final Invoicing and Administrative Closeout

Final invoices for work performed for our clients through December 31, 2025 are being issued and we are settling CSI’s obligations and dissolving the business.

Clients who wish to maintain continuity of engineering and technical support can work with the same engineers who had been providing these services through CSI. Craig W. Trygstad, who was CSI’s Engineering Manager since 2020 and had worked on CSI client projects since 2015 can be contacted at: craig@tryginc.com
