About

Oscar G. Arreola is a passionate advocate for smallholder coffee farmers, originally from Guatemala, who now lives and works in Germany as the manager of Rebel Merchants. Through his role, he’s dedicated to helping coffee farmers in Guatemala, Honduras, and Nicaragua access higher-value markets in the European Union—markets that can offer them a more sustainable and fair income. Oscar’s work revolves around breaking down the barriers that many small-scale farmers face when trying to get their coffee to the international stage. With a background in tropical agriculture, environmental economics, and international development, Oscar brings a wealth of knowledge and hands-on experience. Over the years, he has worked on a variety of education, environmental, and production development projects in Guatemala, Costa Rica, Mexico, and the USA, always with a focus on creating opportunities for farmers to thrive. His work has always been driven by the belief that coffee growers deserve fair access to global markets—access that isn’t just about selling beans, but about building long-term, meaningful relationships that benefit everyone involved. At Rebel Merchants, Oscar is particularly committed to ensuring that coffee roasters in Europe have the chance to establish commercial partnerships that truly make a difference in the lives of coffee producers. For Oscar, this isn’t just about business—it’s about creating a more equitable coffee industry where farmers can thrive, and roasters can feel proud of the beans they source. Every step he takes is in pursuit of a more sustainable, fair, and connected global coffee community.
