Why Sisel?

Sisel stands for Science, Innovation, Success, Energy and Longevity. However, Sisel is more than a name – and more than a company. We’re a community that begins and ends with people like you who want to share health, wealth, and happiness.

Mower Mission

Over three decades ago, the late Tom Mower, Sr. came to a shocking realization: He found that many of the same harsh chemicals used in industrial-strength cleaners were also used in common household personal care items. These chemicals were reported to pose health risks when in contact with the skin. Why would personal care products contain chemicals that do so much damage?

Tom, along with his son Tom, Jr., was determined to spread the word and find alternatives to these potentially harmful ingredients. And so began the Mowers’ quest to produce a historic explosion of activity—a new awakening in the health and wellness community called the Mower Mission.


Tom Mower, Jr.

As CEO and Co-Founder, Tom Mower, Jr. provides oversight and strategic direction for the company and its executive management team. Tom works directly with Sisel’s research and development staff in the creation of powerful new products, oversees the company’s state-of-the-art laboratory facilities, and heads up Sisel’s world-class manufacturing operations.

Tom was instrumental in helping his father, Tom Mower Sr., build Neways into the giant success it became and has been invaluable in launching Sisel as one of the fastest-growing MLM companies in the industry. Tom has a bachelor’s degree in Biology from the University of Utah and is an experienced formulator, scientist, and product engineer. He is credited with developing some of the best-selling products in the health and wellness industry. Tom is a dynamic speaker and presenter and is revered by distributors around the world for his knowledge of nutritional effects in the human body.
