I have been working as a senior executive, manager, consultant and executive coach for almost 30 years. During this time, I have been a board member of two companies (500 and 7000 employees), managing director and partner in a leading management consultancy (PWC Strategy&), manager in a large corporation as well as a found and MD of my own companies.

In these roles, I have led and been (co-)responsible for a great many strategic, cultural, digital and organizational transformation projects and have supported top decision-makers in key endeavours to shape the future of their companies.

I have a degree in business administration and a degree in computer science (FH, ebs) and have continuously furthered my qualifications, including coaching, as a Gestalt consultant and systemic constellation leader. In 2019, my book "Holistic Company" was published, in which I developed a vision for a sustainably successful company in the 21st century, based on a fundamental paradigm shift of its leadership. I am heart@work.

I am Isabell Haak.
I am somebody and yet I am nobody.
I see and yet I am blind.
I remove obstacles and yet I only clean up.
I bring good into the world and yet I do nothing.
I create and yet I am only a tool.
I am heart@work.

As a coach, I have specialised in CEOs and entrepreneurs. As a former CEO myself, I have experienced how classic coaching for CEOs reaches its limits and have therefore developed CEO coaching. This is not pure coaching, but deliberately incorporates elements of counselling and my own experience in order to provide CEOs with the best possible support.

In terms of content, I focus on the topics of strategy, the management team and the role of the CEO.
