Mit Passion für Prävention und Teamwork. Angetreten für Ihre Gesundheit.

Hannes Streeck

Board of Directors of Proactive Medicine AG

"When everyone says, we should actually be doing more in the field of medical prevention, then some must come and just do it. The average 10 chronically ill years at the end of life are largely avoidable, and we want to contribute to making them a worthwhile, healthy, and active time."


Resume & Motivation

20 years of leadership experience in the family business Fiege have taught me that, in life, it is mainly about taking action. It is always worthwhile to invest positive energy into a (life) work. Therefore, it is our drive to create an institution with the Center for Proactive Medicine that keeps medicine understandable for people despite the highest specialization, acts holistically and proactively, and leads to sustainably improved health. The interdisciplinary interplay of Internal Medicine, Orthopedics, and Psychotherapy makes the crucial difference.

Leadership Coaching
