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.

Dr. med. Rebecca Monkman
Fachärztin für Allgemeine Innere Medizin FMH
«Präventivmedizin ist für mich von zentraler Bedeutung. Durch meine Tätigkeit in der Allgemeinmedizin und Neurologie habe ich eindrücklich erlebt, wie viele Erkrankungen erst dann behandelt werden, wenn bereits irreversible Schäden eingetreten sind. Gerade hier bietet die proaktive Medizin die Möglichkeit, durch gezielte Anamnese, Screening-Untersuchungen und Lebensstilinterventionen frühzeitig einzugreifen, bevor eine manifeste Erkrankung entsteht.
In der Neurologie wurde mir besonders bewusst, wie gravierend die Folgen unerkannter oder unbehandelter Risikofaktoren sein können – etwa bei Schlaganfällen, neurodegenerativen Erkrankungen oder vaskulären Erkrankungen des Nervensystems. Die Identifikation von Risikoprofilen, genetischen Prädispositionen sowie frühen klinischen oder subklinischen Zeichen spielt eine entscheidende Rolle, um Erkrankungen nicht nur früher zu diagnostizieren, sondern idealerweise ganz zu verhindern.»

Leadership Coaching
"It makes me alive when I can accompany people in developing inner resources that enable them to have resilience and authentic leadership in challenging situations. Through mindful coaching, I support the medical work.

Based on 15 years of coaching experience and over 10 years in leadership positions across various sectors, I specifically address the individual context and act as a 'sparring partner' for suitable strategies."
