GEUNATOLOSA, a traditional family business

"We have been in the Ox Gallstones business for three generations in our family.
Around 1990, my father Omar Tolosa, started buying bovine subproducts within the province of Buenos Aires.
About 20 years later, me -his daughter- joined the bussines, extending the collection area to new provinces as Entre Ríos, Santa Fe and Córdoba.
I got married in 2012 with Cesar Geuna, who was inmediately part of the company.
Currently my brother joined to the family business too.
Nowadays we work as a team covering the most productive area of the country.
We are actually the only one official buying and selling company of Ox Gallstones in the Argentinean market.
We have our own network of Argentinean slaughterhouses in the central area of the country where takes place 90% of the livestock activity.
Furthermore, we are expanding our collection area to Paraguay, Bolivia, Uruguay and other nearby countries.
Most of our customers are from China, South Korea and Japan. We focus on the highest quality and conservation for Traditional Chinese Medicine.
We look forward to build long-term business relationships with our partners in Asia."
