We love facilitating YOUR leading in three ways: 1) coach YOU in defining and achieving YOUR goals, 2) partner with your L&D team so you have fast, easy control in delivering customized, well-researched learning content; 3) supplement your efforts or assist you in developing teams through leading the delivery of Patrick Lencioni's Five Behaviors of a Cohesive Team workshops.

We also deliver coaching and training on presentation skills for everyone from individual contributors to top executives.

Our Name/Logo

Henry Gantt was a man who made the culture of U.S. industry more competent AND compassionate. With his invention of the Gantt chart, he enabled more effective production and project management, championing social responsibility in businesses. The triangle in our logo is an ancient, cross-cultural symbol for long-term vision. It also represents balancing the triple constraints of project time, cost, and quality.

“While there are many choices available, the Gantt Group clearly stands above all others because of their vast training experience, willingness to work alongside your organization as a true partner, all in an effort to help you accomplish your organization's goals.”
