Mannatech Announces Hiring of Sergio Medina as Managing Director of Mannatech Mexico

Mannatech, Incorporated (NASDAQ: MTEX), a global pioneer in the development of high-quality health, weight and fitness and skin care solutions based on nutritional science, has announced Sergio Medina as managing director of its Mexico business, which is set to open in early 2011.

"Sergio brings to Mannatech a wealth of global direct selling experience and local community ties, and we believe that establishing a presence in Mexico will provide us great opportunity for growth,” said Randy Bancino, president of Mannatech’s international business. "We are confident that our high quality, science-based wellness products and generous compensation plan will be extremely well received in Mexico, and Sergio Medina is the right executive to work with and support Associates and customers in Mexico and, ultimately, throughout Latin America.”

Medina brings more than 20 years of direct sales expertise, specifically in the health and wellness market based in Mexico. Most recently, he was managing director of ZRII since the beginning of its development across Mexico.

Prior to ZRII, Medina spent more than 17 years at Herbalife Mexico. As managing director/senior vice president of Mexico and Central America, he directed all operations, sales and marketing activities, helping the company grow from $6 million in annual revenue to more than $600 million when he left in 2007.

"There are more than 100 million people in Mexico, many of them looking to supplement their income and make a better quality of life for their families, and I believe Mannatech will help them discover that,” said Medina. "That number means opportunity for us, and we plan to show this wonderful country the real possibilities Mannatech has to offer, as well as the unique products that fit perfectly with this market, beginning just two months from now.”

According to the Direct Selling Association, Mexico is the sixth largest direct selling market in the world. Currently, more than two million people living in Mexico are involved in direct sales, and they have created more than $3.5 billion in revenue.

Mannatech kicks off its second Pre-Launch Road Show in Mexico this week with events in Guadalajara, Monterrey and Mexico City. Individuals interested in these events or in Mannatech’s products and business opportunity can learn more at mexicomannatech.com.
