  • Linda K. Bidlack, MA, PCC

    The world order as we know it is disrupted, and as a leader, you are pressed to move through the fog even as you have lost the ground under your feet. Your colleagues are anxious to return to ‘normal,’ while the only real choice is to figure things out together. They need a leader who can find stillness in mid-air to think, like a hummingbird, to listen, to notice what others miss, to help make sense of it, assess the risks, and decide what to learn next while everyone else is running around with their hair on fire.

    You will already have discovered that the way forward is not to add more hours to your workday, and this squeeze is your best laboratory for learning. It’s uncomfortable. All those strategies and habits that worked so well to get you this far have gotten out of sync with the increasing complexity of your role.

    Fortunately, by applying recent insights from neuroscience, psychology, physiology, and ancient wisdom, coaching creates a structured path to thoughtfully apply practices for quieting the noise and cultivating your ability to see clearly and act wisely despite the fog. The artistry of real leadership becomes available to you as you let go of earlier tendencies to control and learn to fly.

    With a background of over 30 years in corporate anthropology, leadership development, and an M.A. in Counseling with client organizations ranging from Goodwill, Paypal, Capital One, NASA, and the White House, Linda served on the faculty of the Georgetown University Leadership Coaching program and holds a Profession Certified Coach credential from the International Coach Federation. Also a founding partner in ChoicePoints Learning, LLC, a diversity and inclusion firm, Linda lived in Haiti as a child, igniting her lifelong interest in building bridges across differences. In her free time, she volunteers for Braver Angels, a grass-roots movement to bring even numbers of liberals and conservatives together for workshops based on marriage counseling exercises to depolarize America.
