Hello, I am Lia!

I am consultant in business development with more than 15 years experience in marketing and sales in B2B and B2C businesses.

I am passionate about psychology and business development. I like to advise and support B2B clients to understand their markets, their potential and to realise their plans in terms of projects or sales growth in France and in the Netherlands.

I grew up in the The Netherlands. The dairy farm of my parents gave me the love for nature and entrepreneurship. I am proud to tell that I am still taking part in the family business today.

I am happy to live and work in the beautiful City of Light, Paris.

I designed and created Rhetolia to translate my ideas into a concept. Rhetolia comes from the Greek word ‘Rhetoric’ which means the ability to see what is persuasive in any given case. This is exactly what I am looking at with my clients every day!
