Who We Are

Roundstone specializes in high performance leadership, change management, and cultural transformations. In these times of constant, often radical change, human relationships based on trust and respect are essential to building an agile and resilient workforce. People need to learn and adapt quickly, communicate reliably, and work together more effectively then before. We achieve this symbiosis, by revitalizing an organization from the inside out -- revealing the areas within the collective beliefs, interpretations, and habitual actions that are inconsistent with the corporate vision and purpose.

We at Roundstone, are inspired by the magic of people learning and coming together. Understanding that moving from an old paradigm into the new is not a prescriptive venture –– rather a social, cultural, and conscious collective effort. We empower people, giving them tools to sculpt a new tomorrow: by coaching people, teams, and companies, to deal with issues up front, using honest communication in the now. In short, our work allows our clients and their companies to let go of the past, design in the present, based on the future they wish to create.
