Stéphane Riesen, new CEO of Pittet Associates


Effective 1 January 2020, Stéphane Riesen is the new Chief Executive Officer of Pittet Associates Ltd. He replaces David Pittet, who held this position for more than 15 years and opted to reorient his career following the company’s acquisition by the Vaudoise Assurances Group last summer.

After graduating in actuarial science from the University of Lausanne and becoming an accredited pension actuary, Stéphane Riesen started at Pittet Associates (now known as MP Actuaires) in 1999, joining founder Meinrad Pittet at the company, where he discovered the world of pension funds and learned the practice of actuarial consulting. Having become a key member of the company and valued for his abilities as a speaker and communicator, Riesen quickly progressed to become the head of the actuarial department. He spearheaded the growth of the department by acquiring new clients and by taking a major role in opening our offices in Lausanne, Bern and Sion.

Stéphane Riesen is a specialist in the financing of public-sector pension funds in a mixed financial system. He serves as an expert consultant to many important public pension institutions in the French-speaking part of Switzerland He has also supported a number of large pension funds in the merger process. Furthermore, Riesen is responsible for handling major private-sector clients in his role as accredited pension actuary, as well as working as an actuary-consultant for IFRS and US GAAP.

“For me, explains Stéphane Riesen, being appointed CEO of Pittet Associates is both a great honour and a great challenge. It’s a great honour because this is the company in which I have learnt the consulting business and spent my entire career to-date. But it’s also a great challenge because the world of occupational pensions is undergoing tremendous change. Pension funds are confronted nowadays with new constraints and new requirements. This means we have to fully grasp the new environment in which we are operating, and find appropriate solutions for it, by applying the professionalism and commitment that have always set us apart as a company.”
