Our Mission

To promote an economically, ecologically, and socially healthy community. We will achieve our mission by applying the sustainability framework through action teams, community outreach, and a democratic, highly participative decision-making process embodying diversity, equity and inclusion.

Statement of Purpose: Connecting people in service to the future

The purpose of our network is to connect people who have a passion for building a bright future for our children, so that they may support and inspire each others efforts. The Network does not take a position on particular issues or require everyone to agree on strategies. However, we will connect those who wish to work towards common goals, lobby in favor of specific initiatives, or work on projects with each other. We will facilitate lively presentations on various topics, providing inspiration and education for our members. We encourage all actions to support our vision, mission, and sustainability framework.
