Her deep understanding of the theories and science of organizational dynamics, blended with her natural intuitive understanding, make her a powerful trusted adviser for any leader.

    Kaihan Krippendorff, CEO, Outthinker

  • As a leadership coach, Shannon has journeyed with me through the challenging process of launching a new program.  The most helpful coaching moments for me have been when she has heard the angst in my voice, and asked me to pause and get in touch with what was really going on.  She slowed me down and helped me see beyond surface issues to the deeper, underlying currents – allowing for more sustainable solutions.  By attending to both me as a person and leader, and to the program I have been responsible for beginning – she helped me make connections, increase my capacity to ask others for support, and develop a program that is moving into its fifth year!  She has known when to challenge me, and when to stop and listen to my struggles.  She has named things I could not see because I am so close to the work, and helped me develop a structure and framework for what we are trying to accomplish.  I am so grateful for her coaching support!
