EWH-USA was formed by Earl and Cathie Campbell in 2012. The Campbell’s operated a highly successful E-waste organization for many years.  In 2012, they sold a portion of their interests and decided to pursue another course of business.  In 2013, Ms. Campbell reached out to a longtime friend Robert Polanco for assistance in what has become a very successful partnership. Combined, Ms. Campbell and Mr.Polanco have over 60 + years of sales experience.  Today EWH is helping many OEM and distributors sell off much of their excess / obsolete material to alternative sales channels.
