About Trumbull

The town of Trumbull is a vibrant community that combines small-town New England character and charm with extensive retail, commercial, and light manufacturing activity.

A wooded setting coupled with a lower cost of doing business continues to drive occupiers to Trumbull.

Commercial properties here are easily accessible via a variety of routes such as Merritt Parkway, I-95, Route 8, Route 25, and the Monroe Turnpike. These access points have drawn the interest of major retailers such as Home Depot, Walmart, and the Westfield Trumbull shopping mall.

Trumbull remains an attractive area to score talent as a significant portion of the population here has obtained a four-year college degree, with a notable percentage of college graduates in STEM fields.
