In response to an overwhelming demand for drug abuse treatment services, the Matrix Intensive Outpatient Program (MIOP) was implemented in the Philippines. This study explores the lived experiences of interventionists in drug rehabilitation programs in Tagbilaran City. The researchers conducted a criminological research approach, specifically a qualitative design, in which the researchers used a Key Informant Interview (KII) with the help of an interview guide, field notes, and a voice recorder to collect data. The researchers used Colaizzi's approach to analyze the transcript material from the informant's comments during the interview. Responses were transcribed in a line format to code the significant statement, and linked statements were given defined meanings. After core meanings were given, they were filtered to produce cluster themes, and grouped again to formulate emergent themes as follows: Inter alia, inter alios (Among other things or between other persons.), Docendo discimus (By teaching, we learn.), In absentia lucis, Tenebrae vincunt (In the absence of light, darkness prevails.), Respice finem (Consider the end.), Sapere aude (Dare to know.), Acta non verba (Deeds, not words), and Ad Meliora (Towards better things.) as the study's outcomes. This research shared the lived experiences of drug interventionists which would serve as a guide in developing sustainable programs concerned with rehabilitating drug surrenders.
