Global and Regional Leadership Teams

As a company who thinks globally and acts locally, Kemin has both global and regional boards of advisors and leadership teams. This allows our leadership to provide both global and regional strategic direction and insight to support the long-term growth of Kemin.

Kemin is comprised of 14 independently operated business units worldwide, each with their own president, leadership team, industry focus and regional customer segment. This structure helps each business unit act locally, strengthen their expertise in the industry and provide specialized solutions that truly meet their customers’ needs.

While each business unit operates independently, many of the insights, best practices and breakthroughs can be shared and applied across the company. This allows Kemin to continually evolve, improve and strive toward our shared vision to improve the quality of life.
