To explore the role of gender and trust in mentoring, fifteen interviews with mentors were conducted. Eight mentors were male and seven were female; eight were involved in cross-gender mentoring. Subjects were asked to discuss the levels of trust they had developed in their relationships, and what had influenced its development. Interviews were conducted by telephone, transcribed, and analyzed independently by the two authors. This paper will present these findings and discuss future avenues of research. Practical implications to mentoring program designers are also discussed.
