Celebrating 15 Years of Design Excellence

As COR3 Design celebrates its 15th anniversary, the Greenville-based architecture firm is also marking another milestone: being named a Best of South Carolina winner for the third consecutive year.

Founded by Brian Doiron in 2011, COR3 has grown into a nationally recognized architecture and design firm licensed in 38 states. Over the past 15 years, the company has built a diverse portfolio spanning retail, commercial, industrial, hospitality, senior living, multifamily, and mixed-use developments while maintaining the personalized service that has defined its success.

Guided by its philosophy of “Design Driven, Relationship Focused,” COR3 approaches every project as a partnership. The firm's collaborative process emphasizes clear communication, innovative design, and practical solutions that help clients navigate complex projects with confidence. From initial planning through final design, COR3 is committed to creating spaces that are functional, efficient, and aligned with each client's vision and goals.

That same people-first mindset extends to the workplace culture, where flexibility, trust, and teamwork empower employees to deliver exceptional results.

Fifteen years after opening its doors, COR3 continues to grow by staying true to its founding principles: strong relationships, thoughtful design, and an unwavering commitment to client success. Its 2026 Best of South Carolina Award reflects not only architectural excellence, but a reputation built on trust, service, and lasting partnerships.
