Darrin Peterson


For more than 15 years, Darrin Peterson has worked in the natural products industry as a leading sales agent, retail store manager, and co-owner of a small manufacturing firm. He has consulted for some of the largest companies in the channel and currently serves as Chairman/President of LifeSeasons.  Darrin serves as VP of Treasury for GEMS.

He shares an experience from his first trip to South Sudan.“Many of the mothers in the NBG are faced with decisions none of us would even consider. Without the basic necessities of food, water and medical assistance, a mother will have to decide, ‘Which child do I choose to let live?’ Take a moment to imagine this. I shared this with my wife over Skype, who is now expecting our 10th child. At that moment, we sat in silence and cried. At times, it is overwhelming, and you can easily slip into a feeling of hopelessness, but when you consider the ‘one,’ you are again filled with the passion a young, developing country needs. With an under-five infant mortality rate, one of the highest in the world, this country seeks help and the ability to live once again a life of passion.”
