Why?
We believe real growth happens just outside your comfort zone , together and guided by people who know what responsibility in the field actually means.
Integrity. We're honest about difficulty, risk, and what an expedition really asks of you.
Community. The connection doesn't end when the expedition does, you join a wider Søre community.
Resilience. Built together, through controlled challenges in nature, guided by an experienced team from Belgian Defence, healthcare, and the climbing scenery.
Professionalism. We work only with people trained in high-responsibility environments — safe, structured, grounded.
Respect. Open communication within the team and with participants, so we can face challenges together and grow from them.
Who?
Founders and headguiding
Mike
For eight years, he served in the Belgian military as a reconnaissance infantry soldier, taking part in various deployments and developing a wide range of skills and experiences.
After leaving the military, he continued his path in service by becoming a nurse, where he discovered a strong connection with both emergency care and mental healthcare. Along the way, he realised that the lessons learned in the military and healthcare worlds could come together to create meaningful experiences for civilians seeking challenge, growth, and connection.
Several years of guiding-experience in the Balkan region became one of the foundations for Søre Expeditions, where he got inspired to bring these different worlds together through outdoor experiences.
Outside of his work, he has been passionate about climbing for over ten years. He feels most connected when surrounded by nature, facing a little discomfort, and discovering what lies beyond his own limits.
Sander
The core values that guide his life are movement, nature, growth, and connection.
As a child and young adult, he sought physical challenges through sport. Over time, he realised that more kilometres or higher mountains matter less than what happens in the mind. What happens when your feet are tired, yet there is still a long way to go?
On a mountain, your job, success, or status don't matter. What matters is who you are, how you deal with discomfort, and how you respond when things become difficult.
Nature, a strong group, and physical challenge have taught him some of his greatest lessons.
His own search for personal growth led him to study sport and exercise, NLP, and Intermittent Living, serve in the military, and invest in books, courses, and coaching. Today, he helps people become more resilient and self-aware through physical challenges, breathwork, cold exposure, and walking coaching.
If your paths cross, he looks forward to sharing that experience with you.
Guiding Team
Jenneke Deelstra
Jenneke is a general practitioner and Deputy Head of Medical Student Education at the UMCG, where she is helping shape the new curriculum for future physicians. Her goal is to train doctors who approach health and human consciousness in a holistic way.
Alongside her emergency care work, including the "GP on the ambulance" pilot, she sees herself as a coach who blends conventional medicine with personal and spiritual development. She works with healthcare professionals, academics, and others seeking growth, emphasizing movement, connection with nature, and releasing old conditioning.
She is a mother of three and a dedicated Ironman triathlete: she describes her third Ironman as a breakthrough where less training and more gratitude led to a faster time, which she sees as proof that beliefs can shape physical performance.
