Firm Profile

Cornerstone Architectural Group was incorporated in 1993. We are a 15-person firm with 4 principals, including 2 founding principals each with more than 35 years of professional experience. Cornerstone realizes that architectural design demands a sensitive balance of diverse and sometimes conflicting elements, and we have focused our professional careers on consistent, functional design for public and private clients.

We have been continuously involved in multiple public school projects; designing and constructing new as well as remodeling and modernizing existing buildings, to provide welcoming, flexible, functional spaces that respond to both traditional and creative innovative models of education.

Our building envelope division provides long lasting and sustainable building envelope and solar design solutions for new, existing and historic buildings. Our team of consultants are highly qualified and experienced. We provide investigations, condition studies with recommendations, and development of bid documents.
