Through the historical study of the corporate and technological changes experienced by doctors in São Paulo in the 1930s, we intend to identify how changes in the fields of equipment and knowledge came from the emergence of specialties, which led to corporate changes and rearrangements in the face of the dilemmas introduced by the Getúlio Vargas government and its policy of centralizing power. Connections are pointed out of a symbolic and representative order, backed by doctors considered 'old-school' and those that represented the 'new' times in medicine, evidencing the clashes between these currents vis-à-vis the specialization movement and particular landmarks in the history of São Paulo.
