From heartbroken single mom to industry legend leading alongside her family

Myriam de la Sierra entered the Network Marketing profession at just 22 years old. With no roadmap and no safety net, she jumped in headfirst - and never looked back. In her first three years, she built momentum with an American company that suddenly shut down its operations in Europe. Rather than give up, Myriam and her husband launched their own company from scratch. For the next 20 years, they built a wildly successful fashion business across Spain, Portugal, and France.

But life doesn’t always go according to plan. After her marriage ended, so did the business. Then came a new partnership, a new company, and a painful lesson: sometimes you earn, and sometimes you learn not to have a partner. That chapter ended in total loss. Myriam lost everything—and found herself a single mom of two with nothing to fall back on.

It was in that moment of crisis that she restarted her Network Marketing journey—this time as a mother, a fighter, and someone who’d already been to the top and back. Over the next 18 years, she rose again—this time reaching the highest ranks of her company, and building a powerful business alongside her sons and new husband.

Her story is one of relentless reinvention, quiet resilience, and fierce feminine power. She’s proof that success isn’t just about one big break—it’s about what you do after the breakups, the bankruptcies, and the breakdowns.

Myriam, like other Mastermind Event faculty members, you’d only hear from her inside her own organisation but like the other speakers, she’s committed to giving back to the profession and showing others what’s possible.
