THe Sixth Level Collaborative

About Us

We’re psychologists, executives, facilitators, and educators who’ve experienced the very challenges we now help solve. The Sixth Level wasn’t born in a boardroom — it was built in real workplaces, through real work, with real people.

Overview

The Team Behind the Transformation.

The Sixth Level exists to elevate leadership beyond performance metrics and into purpose, connection, and sustainable results. We help leaders and teams step into their full potential — through culture, collaboration, and evidence-based human dynamics.

This is about transforming not just how people work, but how they relate, lead, and thrive.

Our Story

From Theory to Practice

The Sixth Level emerged through years of collaboration, research, and real-world experience.

Created by a psychologist, a sociologist, a practitioner-scholar of management, and a business executive, the model was born from a shared realization: traditional leadership frameworks weren’t working. They often overlooked what truly drives people — connection, equity, and shared purpose.

We studied leaders who were doing things differently — many of them women — and quietly creating cultures of trust, innovation, and belonging. Their stories, along with our own, shaped a model grounded in Self-in-Relation: a leadership approach rooted in mutual responsibility, purpose, and relational intelligence.

The Sixth Level isn’t just a framework. It’s a reflection of what’s possible when we lead with humanity.

What is the Sixth Level?

Sixth Level leadership qualities have been ignored for far too long.

The Sixth Level advances leadership for all leaders. The Sixth Level model is derived from the narratives of 16 women leaders as seen through the lens of Self-in-Relation theory, which defines the psychology of women as oriented to connection and care. This model supersedes Maslow’s fifth level, self-actualization, which is based on men’s psychology and is consequently incomplete. 

The Sixth Level model features four core differentiators, qualities that distinguish women’s leadership. These differentiators—mutuality, ingenuity, justness, and intrinsic motivation—redesign leadership. The differentiators promote a collective interest to create healthy social dynamics that, in turn, optimize business results. Women are naturally oriented to exhibit these differentiators, but they can be learned, just as dominance has been learned by women.

The four core differentiators expand the notion of leadership by highlighting qualities in women, long misinterpreted as weak, as essential strong leadership qualities. Finally, the command-and-control model can be left behind. Dominance will no longer be confused with leadership. For the first time, essential aspects of women’s social psychology are defined, reshaping a shared reality that improves the quality of human interaction and improves profitability and sustainability in business.

Let’s start with a conversation.
