Andy's guest on this week's Connected Leadership Podcast is from the US. Debbie Heiser is the founder of The Mentor Project, a global project to bring mentoring and support to school and university students. The Mentor Project has successfuly brought together a volunteer community of high achievers across the spectrum. Andy and Debbie explore a new perspective on this subject, lateral mentoring.  They compare hierarchical, lateral and reverse mentoring emphasising the need to both be a mentor and a mentee. Debbie believes everyone has mentors even if they are not always aware of it; this is the strength of lateral mentoring. Mastermind groups, other types of formal and informal mentoring and issues of reciprocity, vulnerability and diversity are part of this discussion.
