Later he travelled to Tucumán to visit a sugar mill (similar to those that his parents had: ‘Mon Rocher’ and ‘Saint Antoine’), called San Pablo and which was founded by the aforementioned François de Chazal, who had arrived in that region of the Río de la Plata in 1890, hired by the Argentinean government, along with another French engineer by the name of Jean Marie Nougués.

The Count of Blemond, a friend of the family, convinced Guy of Chazal to visit Santa Cruz de la Sierra (Bolivia), to get to know its many natural attractions which effectively impressed Guy de Chazal’s young spirit. After a long trip on horse-back, he arrived in the warm city of the Bolivian east, masterfully described by the French historian Alcides D'Orbigny, characterized by its beauty and charm, kindness and its people's hospitality, as well as the beauty and charm of its women. There he met Georges Roumá, who acted as President of a Belgian mission for educational cooperation; Mr. Roumá played a decisive role in Guy de Chazal’s academic inclinations that prevailed over his military career, which he abandoned, despite strong family traditions. This attitude caused him to become distanced from his French family, whose siblings cut off all relationships due the fact that Guy de Chazal preferred to follow an educational mission instead of military school.

Guy de Chazal won the people's respect and esteem, calling him affectionately call him "Don Guido"; he devoted himself to teaching French, English and history, amazing youth from Santa Cruz with his impressive culture and his accounts of the ideas he had from his educational inspiration, many of them a faithful testimony of his experience on the Old Continent. His noble dedication was recognized at that time by the community of Santa Cruz, who very much appreciate gifts and honourable behaviour, which came naturally to a French gentleman who had come to settle down in Santa Cruz, appointing him as Principal of the famous ‘Colegio Nacional’ (National School). Through Guy de Chazal’s initiative the school’s name was changed, adding "Florida" to pay homage to the Battle of the Independence War that gave pages of heroism to the people of Santa Cruz. (The name is currently maintained as ‘Colegio Nacional Florida’). His passion for nature led him to purchase two properties: the first one, in the area which is currently is the neighbourhood of Hamacas, named "La Esmeralda." (The Emerald). The second one, next to the other one and adjacent to the current Canal Isuto (Isuto Canal), was acquired from Mrs. Aureliana Echazú, and was named "Villa Emma", honouring Mrs.Echazú’s beautiful daughter, Emma Justiniano Echazú, with whom Guy de Chazal fell in love, marrying her in November 1917. Several years later, in 1939, he purchased another piece of property in Porongo (Ayacucho), "Nueva Niza" (New Nice), from a famous person from Santa Cruz, Don Germán Callaú, and later another one from Don José Gabriel Roca, named "La Esmeralda", as a remembrance of the first property, in order to industrialize coffee and produce alcohol. On this last property whose memories are unforgettable for the venturesome and hard working people of Porongo, his six children from his genteel Santa Cruz wife, were born.

Guy de Chazal Trouchet, besides being a high school teacher, a teacher of generations, and having been appointed twice as Principal of the famous ‘Colegio Nacional Florida’, also taught at the Universidad Autónoma Gabriel René Moreno (Gabriel René Moreno Autonomous University) in the Faculty of Economics and Financial Sciences, where he was especially invited by Dean Dr. Rómulo Herrera. Given his French nationality, he was Head of Santa Cruz's School District, President of the Sports Committee of Santa Cruz and Founder and Director of the School of Commerce. He was also honoured with the representative mission of becoming France’s Consul in Santa Cruz, and during the Second World War he coordinated the French resistance in Bolivia with the De Gaulle Committee.

In general, beginning with his arrival in South America, he dedicated his life to education, to training youngsters applying sound ethics and morals; he also, dedicated part of his time to productive work in agriculture and agro-industry, which was an activity that was beginning in the first half of the century, when the bases for the economic take-off of the Bolivian east were established, with the support of the first institutions that were organized in Santa Cruz. He sprinkled his relationships with the cordiality, honesty and naiveté that are characteristic of the Europeans who came to the Promised Land to stay in it.

This noble founder of a family in this part of Bolivia suffered health problems due to high blood pressure, due to some family issues that were increased by the early passing away of his son, Renato, on 8 April 1948 in Sucre (Bolivia) and to economic problems caused by some unscrupulous people who, taking advantage of his righteousness and unchanged honesty, easily found ways to gain his trust and then by means of absurd economic operations, caused considerable decrease in Guy de Chazal’s patrimony, which was built on the base of his own effort and great intelligence.

Guy de Chazal Trouchet passed away at the age of 65, far away from his native Paris, on 31 March 1949, in San José de Chiquitos, during a visit to his eldest son Rolando, who was working as Resident Engineer for the Bolivian-Brazilian Commission during the construction of the Corumbá-Santa Cruz railroad.

A fearsome southern tropical storm known in the Bolivian east as a “surazo” hit the region with torrential rains and an unprecedented storm, amid large black clouds, like a fatal prelude, precisely on the day when the mortal remains of this notorious man who, in the words of Rousseau, was an "illustrious homme et a noble citoyenhe” were going to be taken to Santa Cruz in a chartered plane, rented from Panagra Air Lines.

During the funeral, two Secretaries of State were present and who separately coincided in praising his high qualifications and qualities, identically affirming that: "Don Guido de Chazal was not only a gentleman, but he was a great gentleman in the whole sense of the word."

The multitudinary farewell of the great people from Santa Cruz, who attended the funeral without differences, witnessed the affection and deep respect they felt toward the French nobleman who came to Bolivia just by chance, founding a family, that educated and trained hundreds of young people, carried out agro-industrial and agricultural activities in a business like manner, and left a legacy of honesty, which is still remembered by the noble citizens who are today the true patricians of the community of Santa Cruz.
