In this thesis we explored the best and fastest ways in which mini MBA seminars may enable enterprise owners and employees to gain competencies for the successful management of an enterprise, which will enable them to become more competitive in providing services on the domestic market and become better prepared to enter foreign markets. The problem in focus of this research is the fact that small family entrepreneurs do not possess sufficient professional competencies and skills, which results in their underdeveloped potentials for managing the family business in a way that will enable them to achieve better competitive advantage. In our research we explored the possibility of creating mini MBA seminars in one small family business, Dentaderm d.o.o., a Zagreb-based dermatological and dental clinic. The main goal of the research was to create an adequate program for conducting mini MBA seminars in a small, family-run business. Several research techniques were used during the course of the research: a survey research method, or to be more precise, in-depth interviews, and methods of exploratory research. The findings show that the majority of 6 entrepreneurs, who have their own healthcare family businesses, have little experience in conducting mini MBA seminars. However, they are ready to finance local or foreign lecturers and/or consultants in order to acquire additional knowledge and experience and thus achieve long-term success of their company. On the other hand, findings of the survey including 6 consultants show that consultants believe that entrepreneurs, since they lack experience, are most deficient in competencies and skills of planning and management. The experiences of consultants show that when choosing lecturers and/or consultants entrepreneurs take into account the price, previous success and family recommendations. On the basis of the findings of the conducted research we created a program of an in-house mini MBA seminar for the selected enterprise.
