The aim of this study was to reflect about and discuss the role of a speech-language pathologist with the family of a child with Pervasive Development Disorder. This case study reported the case of a child with Pervasive Development Disorder that attended speech-language therapy from July/2002 to November/2004. The excerpts of clinical material depict the course of the patient's history, emphasizing the significant moments that generated development of the therapeutical process related to oral communication and social interaction within his familiar setting. Clinical strategies focused a favorable physical and emotional environment, promoting constitutive experiences that respect the singularity of each patient, considering the realities of the family and the community it is part of. Therefore, in our understanding, speech-language therapy can be directed towards the creation of situations that promote the process [of each patient] of daily life inclusion, with the respect that all people deserve.
