Bart started SalesQuarters. Bart is entrepreneurial and customer-oriented, with a focus on results. For clients and candidates, this means that their interests take center stage. As co-owner and Partner of Career Openers, a leading Dutch Executive Search agency, Bart gained extensive experience in talent management. Bart worked closely with multinationals like Ahold, Philips and L'Oréal, but also with smaller (often PE-backed / family-owned) companies. Additionally, Bart is part-time affiliated to the Rotterdam School of Management Erasmus University, from where he also got his PhD in sales management (’09), and where he is an active scholar and publishes on leadership and sales management in leading academic journals.
