I've worked with Leon since 1999 when we both worked at SPSS and he hired me to grow the business of the new formed SPSS MR division. In 2006 Leon started the Benelux office for GMI and I had the opportunity to join again as employee #2. In the past 21 years he showed an enourmous positive drive for success, growth, culture and people. Under his smart, strategic but above all nurtering leadership the GMI family and business was born and grown over the years in Mainland Europe. He empowers individuals and teams to become the best version of themselves. We celebrated many succes stories, but at the toughest times Leon really makes the difference, with his profeslialism, positivity and resilience. I personnally feel really honered for working with Leon for such a long time, he is a true leader, inspiration and mentor for me. Any company or individual would be really lucky if they get the opportunity to get to know and work with Leon!

Leon is one of the most positive thinkers I know, he is entirely committed to delivering value to his clients and walks the talk with his can-do attitude. As a leader, he has displayed admirable drive and commitment, not only to the business itself but also very much to the people around him. Leon has enabled both the commercial success and a wonderful team atmosphere across different departments and regions. I believe that any company would be lucky to gain his entrepreneurial spirit and positive attitude.
