Meet the Team

From Operations, Marketing, Advertising, and Design to the Warehouse and Customer Care, Team UMZU is all about helping our customers live a thriving life of abundance and health! Here's just a few of the more than 70 people at UMZU.

Christopher Walker

Christopher is the first person to graduate from Duke University's neuroscience program in just 3 years. Studying a range of topics from endocrinology, to behavioral economics, learning & memory, neurobiology, & AI, Christopher's obsession with human nature and biology helped him to heal his own brain tumor naturally without drugs or surgery.
Disgusted with his negative experiences with the medical establishment, Christopher has spent the past decade creating natural health products and teaching millions of men & women around the world how to use nutrition, strategic supplementation, and physical training to heal their nagging health issues naturally. Your body is a self-healing organism, you just need to allow it to help itself.

Darren Crawford

Darren was born and raised in Port Dalhousie, Ontario (home to Lakeside Park made famous by Rush).

In the late 90s and early 2000s Darren owned a small local bowling center in Middle Tennessee with his family, where he learned the art and science of direct marketing in order to fill the lanes with leagues, casual bowlers and birthday parties. It was also during this time that he learned how to leverage the burgeoning internet to do the same. He was featured in industry magazines for what was then pioneering internet marketing for bowling centers.

The second half of the 2000s was spent in corporate America at Dell where Darren worked with Fortune 1000 companies on their technology needs. This was followed by some Silicon Valley startup in the new Cloud Computing space.

In 2015 the early seed of the idea of UMZU was planted when Darren met his future business partner and co-founder, Christopher Wallker. The business rapidly expanded as the business found its voice and developed a philosophy of researched-backed solutions to help men and women thrive.

Robert Walker

Robert graduated college with a degree in Industrial & Systems Engineering with foci in Data Science and Computer Science. Since then, he's helped grow UMZU through marketing, web development, operations management and data science.

Raised in Virginia, he seeks to take a small-town work ethic to big business by helping grow UMZU supplements into the hands of anyone who needs them.

His hope is that, as UMZU grows in influence, more and more people will understand how powerful nutrition and lifestyle truly can be. He's seen nutrition shrink tumors and waistlines. He's seen lifestyle choices save brains, hearts and even marriages. To Robert, there is no limit to the power of a natural, holistic approach to life and he won't rest until UMZU changes how the public approaches personal health.

He believes that it is his purpose in this life to help people achieve the best possible versions of themselves in all areas of their lives from the physiological being to the psychological and spiritual.
