Horizontal mentorship means to leaders open to learning from each other. As opposed to traditional, hierarchical mentorship where one person is mentoring the other person in a one-way relationship, horizontal mentorship is a two-way transfer of knowledge between executives. We leverage this style of mentorship because we recognize that in order for leaders to get the most out of their executive mentor relationships, there must be a willingness to learn as well as teach in the relationship. When power dynamics become out of balance in a mentor relationship, the longevity and quality of those mentor relationships dwindles significantly.
