Recent testimonials from Gabrielle’s clients:

“Gabrielle is a fantastic speaker. She captivated our audience, and was one of the highest rated speakers by our delegates. She clearly makes the case for why climate change risk is a problem that must be addressed today, while also highlighting why this could be the best investment opportunity of the century. She debunks the myths, provides a clear narrative on what the big issues are, and puts them in an economic context. I look forward to her speaking at more of our Summits this year and would recommend her to anyone wanting an inspirational environmental angle for their event.” Stuart Beyer CEO, Mallowstreet 

“Gabrielle has an extraordinary way of combining an entertaining and humorous presenting style with killer facts about the state of the environment that make you want help her do something about it the minute she finishes speaking.” Clare Crawshay-Williams, Head of Marketing, Weatherby’s Bank

We had an amazing and enriching Performance Theatre in Lisbon that was without any doubt the best ever. Energising , stimulating , mind opening and simply enjoyable. From purpose to leadership to tackling some of the biggest challenges the world faces. This was only possible thanks to Gabrielle's great leadership in not only putting this all together but also by skilfully leading all the key sessions with passion.


I have seldom experienced a moderator who possesses such great skills in bridging different panel participants perspectives, synthesizing their views and outlining potential leanings – without occupying any unnecessary space herself. Gabrielle demonstrates great passion and confidence with the subject matter while treating every panel participant with the greatest respect.

Gabrielle’s talk was the highlight of our sustainability workshop—we got rave reviews. She expertly set up the issue of climate change and plastic waste, and the growing momentum around the circular economy and industry action. Her presentation was simple, relatable, impactful and touched everyone at a personal level. It led to tremendous energy in the room to take action and genuinely contribute towards tackling the issue.


It is rare indeed to find a facilitator who has such a grasp of the subject that she instinctively knows which points to pursue and which to drop and does so with such an effective combination of charm, persistence and firmness.
