Glen Stewart

Philosophy Statement

We are often a little too close to ourselves to notice where we have opportunities to grow, develop, and improve. Coaching gives you the ability to create awareness, plan for change, and take the actions necessary to maximize your personal and professional potential.

Glen Stewart can help you do just that.  An accomplished executive coach, organizational development professional, and CEO of Marquis Leadership, Glen has over twenty years of working with senior leaders across numerous industries to identify and achieve the results that matter most.

Guiding from the side, Glen’s approach to coaching will ensure you are intentionally moving towards your goals, while being flexible enough to allow for the daily situations that influence you along the way.
