who we are

We are a diverse family of entrepreneurial and highly creative individuals who come to work each day aspiring to contribute to the betterment of lives and places.  We are deeply invested in understanding and perpetuating the cultural and historical resonance of the places we are touching. We endeavor to create exceptional value for our clients and communities by aligning with our client’s dreams and projecting them with farsighted vision.  We imagine futures.

The G70 platform has operated as a robust ecosystem for 50 years.

About Us

Our process occurs as a dialogue to go beyond solving problems to finding solutions that unlock promise. We imagine futures, envisioning the strategies that empower people to create them. We engage in active listening, which helps to ensure that each of our employees, clients, and communities are heard. In turn, a deep sense of humility can be felt at G70. This directly impacts our communities, our clients, and the places we all share and love.

We are deeply invested in understanding and perpetuating the cultural and historical resonance of the places we influence. For decades, G70’s mission has been to create exceptional value for our clients and communities. This is achieved by aligning with our client’s dreams, projecting them with farsighted vision for a project’s purpose now and for the future.

The key to G70’s approach is our methodology and work plan. A high quality end product can only be achieved if we work together to focus on obtaining a clear definition of the product which you, the Client, are looking for. It is essential for the success of the project that the method of undertaking it and the organization of the team be clearly established at the initial stage.

About Us

associate principals



LEED AP staff

G70 is committed to developing an economically viable, systems integrated approach to utilities, and infrastructure based on LEED compliant sustainability principles for each of our projects.

We consist of a diverse group of LEED AP experts in sustainable development, design, and research. The objective is to build the most reputable, multi-disciplined, and knowledgeable principals for systems design and integration.

Our principals are changing the traditional model of utilities and infrastructure from expense-based vertical systems to revenue-generating horizontal integrated systems. Design of architecture and interiors are a part of this integration with infrastructure.
