Welcome To Cornerstone

Founded in 1991, Cornerstone Architects is a full service architecture and interior design firm specializing in healthcare, corporate/office, residential (single and multi-family), and commercial (industrial and retail).  Having worked together at Marshall Erdman, a national design/build healthcare firm, founders Richard Morse and Richard Peterson felt strongly their years of experience, coupled with their depth of knowledge in this branch of design, would shape the foundation for a firm dedicated to providing excellence in design services.

Though the years, Cornerstone has become a leading competitor in this arena and has completed many successful projects working with developers, hospitals, private practices, as government agencies such as the Department of Veterans Administration.

Who We Are

We continually seek to understand the client’s experience and we integrate what we learn into our design solutions.
In all our projects, regardless of scale or location, we celebrate our client’s values, goals, and intentions.

Our Services

Project Delivery

The key to any successful project is the open and honest participation of people from all aspects of design; mechanical, electrical, civil, structural, landscape, architectural, and interiors.  Not only does Cornerstone have experience with traditional Design-Bid-Build and Design-Build methods, we also possess the knowledge and experience to act as an effective collaborative partner using any project delivery method.


At Cornerstone Architects, we realize constant communication and understanding amongst the architects, vendors, contractors, and clients are essential ingredients to a successful design and a happy client  As a result, we begin our design process by actively “walking in the shoes” of our clients and their customers.  We do this by immersing our team members in the lives of our clients as well as working closely with key individuals to study and explore their functional “wish lists” for optimized operations.
