About Eng3 Corporation

Eng3 Corporation develops, manufactures, and distributes the NanoVi Eco™, NanoVi Pro™, and NanoVi Exo™ bio-identical signaling devices. NanoVi™ devices serve the health, anti-aging, and sports performance markets. Eng3 was formed in 2003 in Seattle, Washington. International distributors represent NanoVi™ products in overseas markets and Eng3 has a technical representative in Europe.

Our approach is to improve cellular activities without pharmaceuticals. Instead of overriding natural functions by introducing a substance, NanoVi™ devices are designed to stimulate the body’s own oxidative response mechanisms. In this way oxidative stress damage is addressed with no possibility of side effects.

Eng3 leadership

Hans Eng, Founder and CEO
Hans Eng is founder and chief executive officer of Eng3 Corporation. He formed Eng3 several years after moving to the United States from Germany.

Hans’ 25+ years of experience with advanced medical technologies includes Johnson & Johnson in Europe and the formation, growth, and successful sale of a German medical implant company. Hans has deep experience in research and development, production, and quality assurance for medical devices.

A degree from the Technical University of Berlin and his background in material sciences and proteomics enabled him to develop the proprietary technology that underlies Eng3’s NanoVi™ products. Hans’ expertise in medical technologies and his passion for health and athletic performance are reflected in NanoVi™ technology.

Rowena Gates, VP Business Development
Rowena Gates is a principal and the vice president of business development for Eng3 Corporation. She has worked with the company for more than a decade, addressing the health, wellness and performance markets.

Like Hans, Rowena is a serial entrepreneur. Prior to joining Eng3, Rowena spent six years as founder and CEO of Aviarc Corporation, a leader in document chain management. Before Aviarc, she co-founded a document imaging company, now called ImageSource. And prior to this, in 1995, she co-founded one of the earliest companies to offer an Internet-based solution to the logistics industry.

Rowena received a Doctorate from the University of Washington for her dissertation on the use of international strategic alliances by emerging high-tech companies.

The people at Eng3 Corporation have been absolutely marvelous and so polite and helpful and are always there when I need them. Everything I have asked of them they have come forward graciously and I am pleased on all levels. The machine is the quality that you want for a medical machine and it would fit right in my doctor’s office.
