Providing you with years of knowledge, experience and expertise.

Vanessa Judelman, President

 Hi, I am Vanessa Judelman. I’ve been a leadership facilitator and coach for over 20 years. I’ve authored a book about leadership and I’ve been a leader myself.

Over the years, I have trained and coached thousands of people to transition from “doers” to leaders.

I’ve learned that leadership can be really challenging.

It is common for leaders to have a lot of responsibilities, conflicting priorities and challenging “people” related issues.

I have also learned over the years that leaders are “made” not born.

Sure, there are some individuals who find leadership to be intuitive. But to be honest, most people do not.

Plus…so many leaders get promoted into leadership positions without any formal training or development.

So, this is where I come in.

I work with leaders to give them the tools and strategies they need to feel confident, be more self-aware, team focused and strategic!

How did I become a passionate leadership trainer and coach?

Well, early in my career, I worked at a global consulting company developing leaders all over the world. It was in this company that my deep passion for leadership development was first born.

I was able to see first-hand that a better leader equals happier teams and better results.

I have also worked “in the trenches” as a leader building teams and learning to get results through other people. These leadership positions gave me the hands-on experience which formed the foundation of all of my programs. Everything that I teach, I have practiced myself as a leader.

This is why my clients always tell me that my programs are so practical!

So, while leadership can be challenging…it doesn’t have to be!!!

Leadership can be the most rewarding experience ever!

To quote Maya Angelou, “When you know better you do better.” It is as simple as that.

Since founding Mosaic People Development in 2011, I have been fortunate enough to work with thousands of amazing people.

Watching them emerge into talented leaders has been one of the most rewarding experiences of my life.

I am grateful to have a business that I love, working with intelligent, caring people every day.


P.S. Over the past 20 years I have learned that there is an art and science to leadership development. I have created a proven formula to develop results-oriented leaders who feel empowered and confident to do their job. My clients are getting promoted, leading global organizations, increasing their revenue and exceeding their goals!

Let’s talk about how you, or the leaders in your organization, can become confident, self-aware, team-focussed and strategic today!

“Vanessa’s program Mastering Leadership is not just training – it’s a mindset. The course is full of tools and techniques every leader needs in order to manage happy, productive, and successful teams.
