Nick has a thirst for social entrepreneurship and socially responsible business development. In 2007, he incubated a socially-purposed start-up which advocated for disadvantaged property tax payers in Cook County Illinois.

As an advocate of for-profit enterprise as a vehicle for social change, Nick enrolled as a continuing education student and dove into his studies. With its biomimicry focused curriculum, he found the program to be a transformational experience, and discovered new depths of opportunity available in the burgeoning sustainable business movement, not only as a vehicle for building social value, but value for the environment as well. Nick brings his business sense and passion for sustainable business models to bear on his work with STI’s internal operations as well as his development of our Carbon Management program.
