According to his LinkedIn, Justin Rose started his career at Nu Skin Enterprises as a Marketing Services Manager in 1989. Over the years, he worked his way up to more prestigious roles. In 1996, he became Director of Sales at Melaleuca and then an Executive Director of Sales in 1999 at USANA.

At the time of "The Real Housewives of Salt Lake City" premiere, he was working at LifeVantage Corporation as a Chief Sales and Marketing Officer. Justin had been with the dietary supplements company since 2015 and faced legal issues when he and the company were sued in 2018 for allegedly running a pyramid scheme, per Meaww. A man named Brian Smith claimed, "LifeVantage is nothing more than a pyramid-scheme dressed up as a multi-level-marketer of dietary supplements ... Despite LifeVantage's claims of retail sales, little money comes into the system from actual retail users of LifeVantage products disconnected from the business opportunity."

When news broke of the lawsuit, Whitney was quick to defend her husband and told Reality Blurb that Justin was "removed from this lawsuit years ago." Although the lawsuit against LifeVantage is still ongoing, Justin seemed to be thriving in his career at the company. That is, until his involvement with "RHOSLC" got him fired.
