About COR3

COR3’s mission is to bring confidence and security through unmatched service, innovative designs, and efficient schedules and budgets.

COR3 Design is a Greenville-based architectural and design firm serving commercial clients across the United States in a wide range of disciplines ranging from retail and hospitality to industrial and multi-family complexes, and everything in between.

For more than ten years, COR3 Design has set the standard for quality architectural design based on client-centric practices and service. Led by Brian Doiron, the firm was founded with a goal to work more efficiently, with less overhead, and with the client in a higher position of value. Today, those same values steer the leadership team’s daily operations and relationships with clients across the country.

Our Culture

We are proud of the culture we have built at COR3, providing a flexible working environment that caters to the needs and desires of our employees first. Our team is composed of a diverse collective of professionals and an office mascot, our Jack Russell, Rusty.

Our Work

Our early roots began in retail thanks to a strategic partnership with industry developer RealtyLink. We have grown to expand our reach to focus on the following specialty areas: Car Services, Commercial & Industrial, Retail, Hospitality & Restaurants, Senior Living & Multi-Family, Tenant Upfit & Renovation, and Niche Developments.

Our headquarters are located in downtown Greenville, SC but we do work in 30 states around the country and counting. Sign up for our monthly newsletter to see our notes from the field and musings on the industry.
