“I earned my spurs at two international recruitment and search agencies before setting out on my own. What fascinates me about our business – well, many things of course – but if I had to name one, it would be finding out what makes someone tick in life. Rather odd, isn’t it: that money is rarely the thing that keeps people going in their work. A sense of meaning - far more important."

"Outside the office I’m interested in keeping fit; a bit of a health freak, really. I play quite a few sports – of which I practice running most consistently. Married, yes, and with great children, too.”

Hanneke van Vliet
office manager

“Keeping a healthy, friendly and productive work environment is my reason to be at Lens, and I thoroughly enjoy it.“

“I’m also especially keen on welcoming candidates to the office: after all, these people are facing important changes in their life. I like to make them feel at home with a hot coffee or tea and a chat too.

“I’m a real people person myself, so it comes naturally: my free time I often spend meeting friends and family, and enjoying nature by making cycling trips around Europe.”

Bart Heerdink

“My main search area at Lens is the healthcare industry. Executive search is a trade you discover rather than acquire through education: in my case, it was the project quartermaster role I often filled in my earlier career. In design, in architecture and e-culture, I was always in search of specific capacities to fill for the projects and programmes I developed. Today, judging someone’s aptitude for a given position is second nature to me. “

“I find that plain old eagerness is a great tell-tale sign. It’s simple and straightforward: if the prospect of a job excites you, you’re likely to do well at it.”

“Though I’m a real city boy, I do greatly enjoy gardening in my spare time. I also volunteer at the animal rescue.”

Eline Joseph

"At Lens, I specialize in Big Data and commercial accounts. I am fascinated with the possibilities brought by data analytics and particularly the human aspect of data science. Also, sustainability is a matter very close to my heart. Last year I travelled to South Africa twice to support and investigate local sustainability projects and their impact. The first time I looked at solutions for energy resource insufficiency in Johannesburg, and the second time I set up a research project on the impact of water scarcity on companies."

“I love dancing, music, good food and travelling. In my off time you can find me visiting music festivals here or abroad, meeting people from all over the world. I joined Lens, after finishing my Master's degree in Culture, Organisation and Management at the VU University here in Amsterdam, where I live.”

Thomas Pleunis

“My focus is on the financial and the venture capital industry. Family funds, Private equity, quantitative finance & risk management for insurance. High-stakes positions, discerning candidates and clients. I Love it. On the other hand, I’m also committed to the non profit sector – NGOs, foundations: a completely different world.

“I like to think my work makes the world a better place – one person in one better place at a time.”

“An avid reader in my spare time, I devour historic non-fiction as well as fiction. The Hare with Amber Eyes by Edmund de Waal is a favorite, as is any work on art history. Also, I have to visit a museum or an art gallery every now and again, to keep my senses awake.”

“At Lens, I’m involved in search for positions in healthcare consulting, business development, market access – and quite a few med tech start-ups. The drive and passion you see at those smaller firms is thrilling.”

“I’m also involved in the ‘equal pay’ debate - closing the gender pay gap, in other words. It began as a casual talking point in Kennedy Executive, but there are quite a few people involved now, from all across Europe.”

“Details and timing are what matters. Organisations in some industries might all seem the same from the outside: it’s when you look closely that you’ll see why everyone’s leaving this one for the other. That eye for nuance is typical for how I see the world.”

Running Lens Executive Search with Carl is extremely satisfying. My chief area of search expertise is the financial sector: the risk management and big data disciplines, especially. But I’m involved in a wide range of search activities around b2b positions: construction, FCMG, retail… international as well as national, all challenging assignments and hard-to-find people.”

“I take to my work like a bloodhound to a fugitive: I don’t ever give up. Clients have also told me they appreciate how I involve them in my search: I see recruitment as a co-creative exercise in that respect. The more effort we put in together, the quicker we see results.”

“Life is to be enjoyed. From good food to fine wine and from travels around the globe to walks around Amsterdam, my husband and I take the time to get the most from our time on this beautiful planet.”
