Our Vision

To transform the human experience through the power of design

Our Mission

To create innovative, thoughtful and sustainable solutions with our clients

  • Our customer first

    We work every day knowing that we exist for our clients.

    Our clients — whether external or internal — give us the opportunity to design and create. Recognizing that helps us choose clients that align with our values and principles.

  • Innovative by design

    Make design excellence the constant.

    Design excellence is subjective. What isn’t is the need to maximize every design opportunity in everything we do. These small decisions will accumulate, elevating our firm as a competitive design practice.

  • Ethical always

    Insist on the highest moral standards from yourself and others.

    This must be the cornerstone of our firm. At the end of every day, if we can say that everything we did was governed by this principle, we can start the next day.

  • Fair and inclusive

    Respect everyone – appreciate the value in diversity.

    As designers, we understand the value of seeing the world through many different lenses. Our firm, and our work, should reflect the diversity of the communities we serve, and express the genius of that diversity.

  • Responsible

    Own the impact of our work.

    Everything we do impacts the world, both environmentally and socially. Is that impact positive or negative? Are we satisfied by net-zero, or is our work regenerative? We need to understand that impact and keep ourselves accountable always.

  • Never stop learning

    Bravely explore your curiosities.

    Design is all about exploring possibilities. We want to create the kind of place where you are free to try things that haven’t been done before and aren’t afraid to make mistakes along the way.

  • Make it fun

    Love what you do – celebrate the hard work.

    Our principles are a challenge to uphold, but they promise amazing rewards. When you love what you do, you own the positive impacts of your work, and that’s a cause for celebration

Committed to better

  • Great design (and great business) is rooted in sustainability. Our stakeholders collaborate with us to build spaces that withstand challenges, support the well-being of their occupants, have less of an impact on our environment and maximize energy efficiency with high-performance design.

  • We advocate that our projects, workplace and communities are more diverse, equitable and inclusive. We are accountable to fostering a culture of empathy, increasing opportunities in our industry for underrepresented populations and considering the impacts of our work on marginalized communities.

  • A strong sense of community is the heartbeat of life. We pledge to leave the places where we live and work better than we find them by volunteering our time and talents where they’re needed most.

    Some of the organizations we support:

    • ACE Mentorship Program

    • Second Harvest

    • Big Brothers & Big Sisters of America

    • My Sister’s Place
