Jeremiah achieves success with and for his partners through the practice of bias management, cultural competence, and servant leadership. The purpose of this continuing practice is to inspire the best in people and create spaces where people feel they belong.

Instead, teach them to yearn for the vast and endless sea.” – Antoine de Saint-Exupéry
