The Diagnostic Research Education Therapeutic Centre, commonly referred to as DRETCHI opened its doors on November 21st, 1991 as the clinical and technical service function of Trinidad and Tobago Association for the Hearing Impaired (TTAHI) after its first soil turning in 1989.
DRETCHI was created to provide audiological services in order to stregthen and implement the mandate of the Association. The approach to these services was intended to be holistic in its programme development and an impetus for creating educational and employment opportunities for the Deaf & Hard of Hearing (D&HH) community to allow for their full integration into society.
