Our staff is what really sets us apart. The leadership and vision provided by our manager, Geovanny. The depth of knowledge and experience in ranching and farming of Alfredo. The magnetic personality of our volunteer coordinator, Pepe. These all combine to provide an environment that has a sound sense of purpose, based on deep knowledge and experience, in a fun and loving atmosphere. The testimonies of our volunteers over the last fifteen years, provide proof that this is an unbeatable combination.
