Decision support for equitable and sustainable communities

The best efforts to promote social equity and community sustainability are both utopian and pragmatic. They pursue an image of the future that is compelling enough to galvanize support from community stakeholders and impact investors alike. But these efforts are also shaped by a realistic understanding of market conditions, the financial possibilities and constraints, the metrics of success, and the strengths and weaknesses of the implementing organizations.

I Squared Community Development Consulting can help you navigate the challenging realities of realizing your vision for equitable and sustainable communities – assisting you in your role as a “change agent” to inspire people to work together, while backing you up with rigorous research, data analysis, and financial modeling.
