About Us

GPF was founded on a set of values and beliefs that we share with our best clients, investors and partners, as well as the communities we work in.

We believe that: 1) Our quality of life and the success of our economies are ultimately dependent on the long-term health of our environment. 2) Business is the best mechanism for restoring the quality of our air, land and water. 3) The real estate and construction industries bear a moral obligation to minimize negative environmental impacts. 4) Tremendous economic, environmental and social value is waiting to be realized by reducing the waste of natural resources in the design, construction and operation of the built environment. 5) Equity investments in innovative, local green real estate projects should be accessible to a wide spectrum of everyday people.
