Why We Started

In 2002, Marcus Sterling and Elena Rodriguez noticed a major flaw in the construction industry: a lack of communication between architects, engineers, and energy specialists. Projects were falling behind, and sustainability was often an afterthought.

They founded Cornerstone Solutions Group LLC with a single mission: to create a "Unified Build" model. By bringing master carpentry, high-level engineering, and solar innovation under one roof, they eliminated the stress for clients and set a new standard for durable, eco-friendly infrastructure.
