Erin Samaniego

Certified Group Leader, Ventura, CA

My name is Erin Samaniego. I have spent over 20 years in the personal growth and development arena coaching hundreds of people to go beyond their limits and pursue what is important to them. I believe that learning and knowledge are important but what matters most is who you are about your goals; and the actions you take towards accomplishing those goals.

I worked in the corporate world for several years, but I never felt settled. After eight years, the Universe took care of that for me as I was laid off. That was when I was able to fully embrace a Direct Sales business I had been fiddling around with as a hobby for the previous three years.

In just a couple of years of working my business full-time I earned an income, several promotions, monetary bonuses and incentive trips. In one year I was among the top 1/2% of people in the company to earn top awards. I was recognized in the company as a leader and was one of 20 people out of over 45,000 business owners to be published in the 2018 catalog with my story. I have mentored a team of entrepreneurs and have helped many earn promotions, bonuses and awards along the way.

My heart has always been about making a difference and being a business owner. But in my spare time I love spending it with my supportive husband and my two amazing and crazy kids.
