M. Frances Baldwin

I have forty-plus years of experience as an educator, organization development consultant and coach in a wide range of organizations.  Twenty years as an internal to city government and the international petroleum industry; and twenty as an external. The breadth of what I have garnered greatly exceeded my expectations as a public school educator entering this new world of work. I lived and worked internationally. I worked hands on, in board rooms, on shop floors and in castles. I worked aboard Navy aircraft carriers, underground in coal mines, and rode side saddled with police and firefighters. I collaborated with UN representatives in a G20 extension summit on women’s equality.  Clients across these varied sectors consistently remark about my gifts and how I bring them, with intention, generosity and relevance.


That I seem to follow very specific assumptions/beliefs about people, purpose, change and my place….. helping to address the current contexts, and when they are open to it,  embracing the whole of each situation; guiding people on their walk and organizations on navigating the ever-changing world where uncertainty has become the new reality; the global order; changing demands  of workers and markets; defining and adapting to the impact on businesses and societies.

As an elder, wisdom-keeper and teacher; my offering is a unique integration of experience, knowledge, spiritual presence, and fluency for envisioning possibilities. I look forward to being an evocateur with Wicked Company; joining other voices to shape our growth and others in organizations.
