ESI graduates are selling more, earning more and getting promoted!

Having a professional diploma and understanding sales methods makes me standout. ESI changed how I think and I recommend this diploma for anyone in sales and business.

Richie Duignan, Account Executive – Australia

The biggest impact of ESI was in delivering better business outcomes: I have improved my book of business and my forecast for the full year is now higher. My forecasting is simply better – not just how I forecast a month but thinking about the full year.

Andrew Golden, Senior Account Manager – Australia

I hit bonus this past quarter and it’s now the new normal for me. I also see the results in my professionalism, my new attitude and controlling what I can.

Lorri Ann Zelaznik, Sales Manager – USA

ESI’s insights played a role in closing a £500k deal this year. The courses helped us streamline the necessary efforts to seal the deal.

Chris Knight – Account Manager, United Kingdom

ESI has changed the way I work. It has given structure to how we do things in our team and has significantly improved my confidence, especially when calling prospects.

Katarina Varga, Sales Manager – Croatia

It has been really useful as it allowed me to put what I learned into practice without being in sales, and that’s exactly what I need and want to learn.

Mario Suarez, Head of Customer Success – England

Over the last couple of months, I have become a better listener on customer calls and internally, which led me to uncover what might be our largest Western Canada opportunity.

Daniel McCabe – Account Manager, Canada

Despite my three decades of experience in sales, the Business Acumen Micro-credential was eye-opening. It made me rethink how I manage my pipeline and encouraged out-of-the-box thinking.

Scott Major, Sales Director – Canada

As someone who recently moved into sales, ESI has helped me get into a sales mindset. The thing that I like the most is that everything I learn, I can apply in my job in real time.

Oscar Ruiz, Sales Engineer – Spain

ESI graduates come from all over the world and they work at companies like…
