The videos at the top of our pages share a common theme: “panta chorei” – everything flows. Movement implies purpose, with a clear origin and destination. This philosophy mirrors transformation itself – understanding why change is necessary and envisioning a better future and creating impact by transforming complex challenges into feasible solutions. 

Gerrien began her career as a trainee at Rabobank and later served as Global Director of Program & Change Management at KPMG Consulting. She spent nearly four years working abroad as an expat in Washington D.C., New York, and London. Subsequently, she worked at EY’s headquarters as an Associate Director. Gerrien brings over 25 years of experience and possesses a comprehensive background in business management, leading large-scale (digital) transformations within complex, international organizations. She has extensive expertise in operational effectiveness, HR, change and program management, leadership, cultural change, and digital transformation, successfully collaborating with multicultural teams.

She enables C-suite clients in the corporate and financial sectors to realize their growth ambitions by reimagining their position and future, rather than merely perfecting and digitizing existing processes. Gerrien’s strength lies in developing people and organizations simultaneously and in harmony to create lasting value. Through her company GA ERVOOR, she serves prestigious clients including ABN Amro, Rabobank, ING Bank, APG, JDE Douwe Egberts, T-Mobile, CGI, and University of Amsterdam.

Her experience as a non-executieve director in various social institutions has cultivated a keen sense of social responsibility. She chairs the Innovation & Digitalization Committee and serves on the Remuneration Committee of the Examenkamer’s Supervisory Board, which independently oversees examination quality in the private sector. Additionally, she chairs the Audit Committee and School Fund at Marnix College. Gerrien also contributes as a member of the PE Committee at the Erasmus Governance Institute, Erasmus University, member of the Financial Advisory Committee of the National Board VVAO, and member of the Members’ Council VVAO, the association for women with an academic education. In her non-executive roles, Gerrien specializes in the portfolios of HR, legal & governance matters, and organizational development, serving as the chair of the audit and remuneration committee.

With publications in renowned media such as FD and NRC, as well as her acclaimed book, she strengthens her position as an authority in her field. But she doesn’t stop at words—she translates her deep expertise in leadership, organizational culture, diversity, and equal pay into effective, tailor-made strategic solutions.

Gerrien holds a BSc in Personnel & Organization and graduated with a MSc in General Social Sciences, specializing in Management and Organisation from Utrecht University. She completed her post-academic education as a legal mediator and ADR specialist at the University of Amsterdam and finished the post-academic Program for experienced Non-executive Board Members at Erasmus University.
