Purpose: This study analyzes the development of organizational culture in an international subsidiary in healthcare through the interaction of the parent company and local culture. Design/methodology/approach: We conducted a single case study on Elekta Greece, a subsidiary of the multinational company Elekta based in Sweden via interviews. Findings: The company creates a unique organizational culture, called the Philotask culture, that takes into consideration the cultural contexts of Sweden and Greece, the value of philotimo, situation in the market, and the type of company and services. Research implications/limitations: The model consists of a context-grounded framework focusing on healthcare. Research in other countries and industries can help to generalize this model. Practical implications: The findings indicate that to develop organizational culture, managers need to consider the local cultural context. Originality/value: This research contributes to organizational culture theory, reporting on the Philotask model that emerged.
