Firm Principals

Our office operates through a collaborative, open environment, where our entire office participates in the development of the projects we undertake. For each project, two firm principals are assigned to be the design team “head” that participate in the project from initial programming and concept design phases through the closeout of construction. Involvement in all phases of the project’s development allows us to maintain a consistent vision of a project’s priorities through the long construction process. The two principals assigned to the project support each other, one acting as the primary point of contact, the other providing backup and quality assurance functions. Together they manage the design team consultants and keep them focused on the project needs.
