In the summer between his first and second year at medical school at the Mayo Clinic, Eduardo Peña Dolhun traveled to Guatemala and witnessed the widespread suffering and death caused by Cholera, a severe and lethal form of infectious diarrhea.

Having only read about Oral Rehydration Therapy (ORT)  in medical school, it was in Guatemala, that he saw the stunning effectiveness of this life-saving medical technology, which was faster, safer, and easier to use than intravenous therapy (IV).

He credits this experience with inspiring him to pursue an even more effective, better-tasting Oral Rehydration Solution (ORS).
