Collaboration is essential for crafting a process that delivers meaningful and lasting results. Excellence is an outcome of an integrated, creative, and dedicated team that shares specialized knowledge and skills. Teamwork guides project design, implementation, sustainable practices, and management guidance to ensure incorporation of cultural, environmental, social, fiscal, educational and recreational values. Our commitment to equity, justice, and diverse voices pervades collaborations.

We always seek to build lasting relationships with clients and team partners through the project process. Our diverse clients include municipal, state and federal government departments and agencies, museums and institutions, international organizations, not-for-profit entities, and citizen advocacy groups. On our projects, these stewards are full partners in each initiative, articulating goals, shaping project programs, providing data on capabilities, clarifying emerging and perennial issues, weighing alternatives, and jointly making decisions to bring consensus forward for endorsed and supported actions.

As effective members of interdisciplinary teams, we serve in both team leadership and subconsultant roles. We begin from a shared understanding and seek clarity on project intent and objectives to develop an atmosphere of open communication, creative collaboration, and mutual respect that enables all team members to fully contribute. For additional information see our Statement of Expectations for Project Teams.
