“From our team’s perspective, when we closed the doors, and everyone’s camera phones went up like we were at a concert, we knew this was IT! Sylvie was so lovely to work with and an incredible speaker! Her presentation was phenomenal and she was named multiple times as both the top speaker and most exciting aspect of the event. Then we had our biggest sponsor come over and tell myself and my Executive, 'You should be proud'.”
“Sylvie’s talk at our annual conference was a perfect 10!! Her messaging resonated so much with our audience of business coaches, she added some very special touches to customize to our theme (including her awesome suit). It was an absolute honor to have her present one of our marquis awards and the coaches really got big impact from being able to meet her 1:1. Highly recommend Sylvie!!"
