Deepening & Broadening : Through vertically developmental coaching (pre-recorded session)

Session summary: In the last 30 years we at Harthill, along with our global network of, now, 730 Authorised users had the privilege of introducing approx. 13,000 leaders to the Leadership Development Framework and its associated profiling tool, the LDP. Over that time, we’ve learned a lot about adult development, and built a whole body of understanding around how development can manifest, expand and take root, and of the significant and sustainable benefits this can bring to individual leaders and the organisations in which they work. 

More recently we’ve been turning our attention to how we can help executive and team coaches work more intentionally with the LDP, and with other foundational concepts within Vertical Development. And, on the back of this body of research, experimentation, conversation and reflection we are now launching the pathway towards Accreditation as a Vertically Developmental Coach. 

During this session, Sian Lumsden and Rebecca Stevens will be discussing with a couple of other coaches the degree of transformational impact they have witnessed or experienced through working in this Vertically Developmental way in both Individual and Team Coaching. 

“Vertical development can allow a person … to lead from wisdom and expansiveness rather than being stuck in a limiting (and often unconscious) mindset. It changes the culture of the organization for good.”Forbes, Jan 2020
