She leverages her internal leadership experience at Merrill Lynch and her 25 years of experience working with senior leaders and their leadership teams to quickly get to the heart of the matter, ask ‘the’ question that solves the problem and creates the breakthrough, and identify simple yet profound followup actions have clients consider her an invaluable partner with whom they partner in key transition point over the courses of their leadership careers.

What clients are saying…

“Gisele Shelley is so inspiring, facilitating one of our highest-attended webcast on The Myth of Perfection for the Hewlett Packard Enterprise – Global Women’s Network. She has the uncanny ability to connect with the audience on a personal level, providing pragmatic examples that can be easily applied by all. Her session was by far the most highly rated webinar we have ever had. Thank you Gisele!”

~ Meredith Livingston, Executive Communications Manager, Hewlett Packard Enterprise

“I have found Gisele’s coaching to be of significant help in my development as a senior leader.  I have found her to be very balanced between the theoretical and practical.  Both of these things have given her a very high level of credibility with me.  The coaching has exceeded my original expectations and are clearly impacting my own effectiveness and ultimately business results.”

“Gisele is one of the most effective consultants I have worked with in my 30+ years.  She is equally adept at seeing the big picture and ensuring goals are achieved as she is with planning and managing details to achieve flawless execution.  Gisele is skilled in working with individuals at all levels.  She is a highly skilled public speaker with the ability to facilitate large groups to achieve measurable results.”

Director, Leadership Development and Executive Coaching, NASA Office of Human Capital Management

“Working with Gisele has been the most impactful area of my professional development over the course of my career. Our coaching has opened up my views, made my work consistently enjoyable, and I feel confident. Working with Gisele has been a huge impact not because she is a coach, because she is Gisele. Before working with her I felt like a sailboat with no rudder. Now I have a rudder behind my boat, allowing me to steer in the direction I want to go. This has been one of the most helpful things I have ever done.”
