Jessye Kass Karlin believes that the way we hire, lead, and communicate has the power to shape not just workplaces, but lives. Her path into this work is not a straight line, it’s a river of lived experience, leadership, and lessons learned.
Before founding Riverwalker Talent, Jessye spent over a decade in nonprofit leadership roles, often in moments of growth or crisis. She discovered that what made the biggest difference wasn’t just strategy or systems, it was people: how they felt seen, how they worked together, and how they found meaning in the mission.
Over the course of her career, Jessye has guided 100+ searches, coached hundreds of leaders, and facilitated trainings on leadership, conflict resolution, and workplace wellness.
Her perspective is also shaped by her own lived experiences as a survivor of domestic violence and bullying, a queer and differently-abled leader, and someone who has navigated both personal and systemic challenges. These experiences ground her commitment to building spaces where people are heard and valued.
Clients and colleagues know Jessye for her deep listening, her ability to ask the questions others avoid, and her mix of warmth and clarity. She brings humor, honesty, and humanity to her work—whether she’s guiding a search, coaching a leader, or facilitating a difficult conversation.

We stand between multiple sides, bridging the needs of organizations and the talents of individuals, to help both find alignment.
