GRN Vision principal Dave Ray provided professional consulting services as a Sustainability Advisor on a pro bono basis in 2013 for the Downtown Project's 9th Street Bridge Charter School. The Downtown Project is a $350M urban development initiative founded by the CEO of Zappos, Tony Hsieh. The 9th Bridge School project involved a major renovation of an existing historic church and school in downtown Las Vegas. Dave provided operational and maintenance consultation as well as policies and procedures that developed comprehensive protocols for their staff on green cleaning as well as advising on the hiring and training of staff. Dave also provided ongoing support during and after the private charter school launched. This project was undertaken to support education in the Downtown Las Vegas community.
