Diagnostic partnership.
The human plus.

Our team

An experienced team of consultants, the majority of whom are psychologists. With extensive methodological skills, expertise in management diagnostics and leadership and organisational development. Personalities who enjoy assuming responsibility. Every day afresh. Who feel at home in the world of management. Who are fascinated by people and have turned their passion into their profession. Who approach their tasks with integrity and enjoy the trust of their managers – and their clients.

“It’s important for me to fully understand the needs of an organisation. Standard solutions are of little use – as is pigeonholing. That’s why we work with customised approaches.”

— Dr. Saskia-Maria Weh

“In our team, we support each other and complement each other perfectly. That’s special. We’re diagnostically strong, passionate about what we do and eager to experiment. You can only experiment successfully, however, if you build on experience, expertise and specialist knowledge. And that’s exactly what we do! That’s how impressive solutions come about, and it’s so inspiring – not just for us, but for our clients, too.”

— Hannah Irrmischer
