Strategic Partner of ECC.

Marie is a former Fortune 500 Training and Development Executive who applies her business experience and comprehensive portfolio of industry leading skills to coach leaders and top talent to perform at their highest potential. Marie has seen what it takes to be successful and continue to develop in today’s complex, global and constantly changing business environment. She has coached leaders and teams through mergers, re-organizations, leadership transitions, divestitures and the impact of risk and regulatory changes. Marie works with rising top talent who aspire to take on roles of increasing responsibility and impact and must often recognise and re-focus habits and behaviours that don’t serve them anymore. Marie is described by her clients as being able to see the big picture, build rapport quickly and demonstrate she is open to engage with any personal change challenge. She is willing to ask hard questions in service to growth and discovery, working toward practical and solution oriented goals in service to her client’s immediate and long-term success.

Coaching Style

One of Marie’s favourite quotes illustrates her coaching style. “Man’s mind, once stretched to a new idea, never regains its original dimensions.”  – Oliver Wendell Holmes. This concept is very powerful for her because it speaks to the continuous process of personal growth through discovery.   Marie takes a unique but pragmatic and holistic view with each client by asking “Who are you now?  Who do you aspire to be?”  She works with her clients to identify and leverage their strengths and values, assess the style they bring to work, clarify how others see her clients “show up” in the multiplicity of roles they play (e.g. leader, subordinate, peer and manager), and uncover the stories we tell ourselves – in some cases it’s a form of self-talk which is limiting, at other times it’s a view of competence which prevents us from seeing blind spots.  The result is a development plan and actions to achieve immediate and lasting impact and breakthrough results.
