Leadership Perspective
A Strategic Step Foward
“In September 2024, Sentry Commercial acquired New Haven-based Commercial Development Company, marking a significant milestone in our journey toward vertical integration. This strategic acquisition has expanded our geographic footprint, strengthened our service platform, and elevated our project and construction management capabilities. Most importantly, CDC’s people are a perfect cultural fit — aligned in our mission to improve the lives of our clients, our people, and our community.”
