Salary overview

Placements Executive & Senior Management since 2000


Leadership can be defined as “realising meaningful outcomes, for and with people, on the basis of a vision”. The central challenge facing leaders is to create a bond with their team members, their colleagues and also with their clients. When there is no connection, there is no trust and respect either. If leaders can connect with others (peers, team members and clients) and with themselves, this will develop trust and room for more initiatives, more entrepreneurship and more decisiveness both at the board level and throughout the entire organisation.

It is our passion to build high-performance organisations through connecting, Secure Base Leadership!

Quaestus in image and sound

Quaestus Executive Leadership helps organisations to make changes proactively.
We do this by thoroughly immersing ourselves in the organisation and gaining a deep understanding of the company’s structure, as well as the Board Room Dynamics. Directly afterwards we approach those leaders, found & selected via our extensive network contacts and by using a unique multi-channel approach.  After installment, we carefully support them during their first period in their new environment (Onboarding). All of them are leaders with the ability to establish a safe Secure Base environment characterised by respect and trust, who are inspiring and can take an organisation to the next level. Quaestus is part of an international network, ( IMD International Search Group) and also conforms to the strict criteria of the AESC, Association of Executive Search Consultants.
