The paper attempts to describe existing informal practices of relationships’ building between physicians. The study is based on empirical analysis using the technique of in-depth interviews with physicians and heads of medical institutions (57 interviews) in Moscow and elsewhere (Vologda and Kaluga regions). Special attention is given to answering the question: do physicians as professional group feel themselves as autonomous community of professionals or are they collectivist in their work? Do professionals agree/disagree to interact with less experienced physicians and why?
