From Lab to Customer Engagement
I started my career as a medical biological analyst at Amsterdam Medical Center (VUmc), specializing in virology, serology, and molecular diagnostics. As a Senior Core Analyst, I combined technical expertise with training and mentoring colleagues, interns, and physician-researchers
Laying the foundation for my future steps.

Mission
EZ (easy) sales in a complex market
With years of experience as an analyst and senior account manager in Life Sciences, my mission is to help professionals and companies in this unique sector develop effective commercial skills. I aim to bridge the gap between science and business through training, coaching, and consultancy that truly address the challenges of Life Sciences. Whether supporting scientists transitioning to customer-facing roles or guiding those without a biomedical background who aspire to a career in Life Sciences, I help them grow and excel in this fascinating field.
Vision
Training from within
I believe the individual (not the company) is the key to successful sales. Acting from your own strength and authenticity creates real value and deeper customer understanding. In the Life Sciences market, I see great potential in training analysts and researchers to become account managers, fostering personal growth while bridging science and business for stronger relationships and better insight into customer needs.
