What role can a horizontal mentor play in your professional development? Have you ever even heard of a horizontal mentor? Horizontal Mentors are those professional peers to whom one can turn for deeper and more frank discussions, whose advice and judgment about professional and career questions one seeks and values, and whom one can call on for support. The recent rise of "horizontal" mentoring provides the opportunity to build multiple relationships within a professional network and gain insights and advice from colleagues and peers in various capacities. Members of the Getty Leadership Institute's NextGen Class of 2011 led a roundtable discussion during the American Alliance of Museums 2013 Annual Meeting on this topic.
