The purpose of this study was to explore the experience of novice art therapy supervisors using hermeneutic phenomenological methods to understand the process of changing their roles from skilled therapists to supervisors. For this study, data were collected through interviewing with four novice art therapy supervisors. After analyzing collected data, 4 essential themes and 9 sub-themes were defined. The essential themes of the research results were “accepting new offers, unfamiliar roles,” “wearing new clothes called supervisors,” “finding answers to the role of supervisors in art,” and “grow together.” Based on this, the conclusion of the study was as follows: First, the study participants experienced difficulties, although there were differences in degree in the process of changing the role of a supervisor from a skilled therapist. Second, the study participants made the best effort to provide quality supervision for supervisees, which resulted from the ‘responsibility' of a supervisor. Third, the research participants objectively looked at and understood the difficulties they were facing through art and were able to solve them. Based on these results, the implications and limitations of this study were discussed.
