Equal employment opportunity is the law. One-Community Consulting is committed to the practices of equal opportunity and nondiscrimination. We will not discriminate against any individual based on race, color, gender, gender identity, religion, national origin, political persuasion, sexual orientation, marital status, disability, height, weight, veteran status, age or familial status. We celebrate diversity and are committed to creating an inclusive environment for all employees.

Incubation Stewards

As we work to accomplish your goals we also steward the next generation of social enterprise. Too often communities function through a silo’d approach with limited support for those desiring to learn, grow and play within their own neighborhoods. It is our goal to empower not only organizations, but also those desiring to give back while pursuing their own career. That’s why we’re committed to working with our partner “incubation stewards” to leverage further resources, impact greatest change and offer peer coaching for our social entrepreneur associates.

In a world where nonprofits and their employees frequently are asked to do more with less, collaboration and partnership building is necessary. While we may agree on the end goal and steps to get there, what actually happens in the middle between our partners can leave everyone pointing fingers. However, it is possible to build community development momentum even among competing agendas.

“Transcendence” occurs when we move from disgruntled worker to problem solver, from disenfranchised or subordinated citizen/employee to empowered. The purpose of this book is to help provide the reader with tools to do so. But it doesn’t stop there. Within, the reader will move from burned out do-gooder staff to understanding their own overwhelmedness as a symptom of larger and solvable root causation – whether personal, institutional or cultural. Moving past stagnancy, they must embrace change and learn from other sectors realizing “it takes a village”. Then in partnership, the reader transcends their own limitations and lifts the community achieving real collective impact.

Using business supply chain, marketing, communication, psychology and more, the reader will apply strategies that transcend their sectors, roles and positions within the collective community for personal, professional and partnership improvement. Embodying empowerment, the reader must move through each state to understand what transcendence really means for them. Equipped with these tools a change occurs and the spirit of their service may shine.
