• Co-CEO Steve Fenstermacher, Chief Financial Officer – Fenstermacher joined Mannatech in November 1998 serving as CFO where he assures corporate financial accountability, strategy and transparency.   His management responsibilities include: accounting, finance, HR, facilities and IT operations.  During his tenure at the company, he has established a worldwide system to support international growth including the creation of a seamless down line commission system and a global framework to manage and integrate efficiently the company’s financial operations through a Swiss subsidiary.
• President of Global Business Operations and Expansion Randy Bancino, previously Senior Vice President of Global Business Operations – Bancino began working with Mannatech two years ago directing business operations for the company across international markets, as well as North America. He brings more than 20 years of sales, marketing and business experience having worked as an executive with the top direct selling companies in the world.  He will continue to work with the general managers of Mannatech’s international subsidiaries while driving the company’s future expansion efforts.

“On behalf of the Board of Directors and the rest of the Mannatech family worldwide, we thank Wayne for his contributions to the company during the past two years,” Mr. Fredrick said. “We believe his work lays a good foundation for this newly created management structure that will allow us to focus on the success of our loyal Associates who are the future of the company.”
