In this illuminating interview, we sit down with Dr. Dirk Stemper – an internationally renowned psychologist, coach, and author – whose Berlin-based practice, Psychologie Halensee, has become a global hub for personal and professional transformation. With a background in medicine and psychotherapy, Dr. Stemper seamlessly integrates clinical insight, philosophical depth, and executive coaching into a singularly powerful approach. His clients span continents, from executives in Tokyo to individuals in Amman and beyond, drawn to his unique blend of empathy, cultural sensitivity, and strategic clarity. In our conversation, Dr. Stemper shares how he built an international clientele, the synergies between psychotherapy and leadership coaching, and the core message behind his books, including Selbstfindung und Selbstorganisation für Führungskräfte. Whether helping clients overcome toxic relationship patterns or guiding leaders through existential reflection, Dr. Stemper’s work is a testament to the power of integrating mind, heart, and action. This interview offers rare insight into a truly holistic model of personal development.
Q: Dr. Stemper, your practice Psychologie Halensee is based in Berlin, but you work with a very international clientele, including patients and coachees from places like Jordan, the USA, and the UK. You’ve even led team and leadership development with companies in Japan, Belgium, and other countries. How did you build such an international practice, and what is it like working across cultures?
A: It’s true – over the years I’ve been fortunate to work with people from almost all around the world. This international reach grew organically. Berlin is a global city, and many expatriates and travelers found their way to my practice. Additionally, through word of mouth and digital coaching platforms, I began receiving clients from Jordan, the United States, the UK and beyond who were seeking psychological counseling or executive coaching online. I also collaborate with international partners (for example, in the UK and Japan) on leadership development programs. These partnerships have led me to work with executives and teams in countries like Japan and Belgium. I must say, working across cultures is incredibly enriching.
I’ve learned that while cultural backgrounds certainly influence how people approach problems, there are universal human themes – stress, relationship issues, the desire for purpose – that connect all of us. In sessions, I stay mindful and respectful of cultural differences; for instance, the way someone from the Middle East talks about family or someone from Japan approaches workplace hierarchy can differ from a European perspective. By listening and learning, I tailor my approach to each individual’s cultural context. Ultimately, I find that authenticity and empathy are languages that everyone understands. Helping a client in Amman or an executive team in Tokyo navigate their challenges comes down to building trust, showing genuine respect, and applying sound psychological principles. The reward is seeing that despite our different upbringings, we can create understanding and growth in the same deeply personal way. It’s a humbling reminder that we truly live in a connected world, and it inspires me to continue learning from every client, no matter where they come from.
Q: One thing that stands out about your work is how you combine psychotherapy, philosophical reflection, and leadership coaching. That’s quite a unique mix. How do these disciplines intersect in your approach, and why do you believe this combination is beneficial for your clients?
A: My approach evolved from my own journey and curiosity. I originally trained as a medical doctor and then as a psychotherapist, so I’ve always been aware of the interplay between the body and mind. Early in my career I held leadership positions in healthcare organizations, which got me involved in coaching executives on how to shape both individual and organizational health. At the same time, I’ve been a lifelong student of philosophy – I love reflecting on the “big questions” about meaning, values, and what it means to live a good life. Over time, I realized that these three paths – therapy, philosophy, and coaching – aren’t separate at all. In fact, together they form a powerful triangle for personal growth.
In my daily practice, this means I don’t just treat psychological symptoms in isolation or just give surface-level coaching tips. I try to address the whole person. For example, if I’m working with a client who is a CEO under a lot of stress, I might use psychotherapy techniques to help them understand and manage their anxiety. But I won’t stop there – I’ll also draw on philosophical reflection, encouraging them to explore questions of purpose, identity, and values: Why do they do what they do? What kind of life and leadership legacy do they want to create? This deeper exploration often brings powerful insights. And then comes the leadership coaching element – translating those personal insights into action: How can they lead their team more effectively? How can they communicate their vision with empathy and clarity? By blending these disciplines, I’ve found that clients not only overcome challenges (like overcoming depression or improving team performance) but also gain a richer understanding of themselves. It’s beneficial because life isn’t one-dimensional. Leaders have emotions, people in therapy have workplace struggles, and all of us grapple with existential questions at times. By combining modalities, I can fluidly move – in the same session even – from healing past wounds, to strategizing about a career decision, to discussing a quote from Stoic philosophy. This holistic method helps clients achieve not just immediate goals but also long-term fulfillment. Many have told me that this integrated approach made them feel seen as a whole person, and for me that’s the ultimate goal: to help someone align their mind, heart, and actions in harmony.
Q: You’ve also put your ideas into writing. One of your publications, Selbstfindung und Selbstorganisation für Führungskräfte (which roughly translates to “Self-Discovery and Self-Organization for Leaders”), focuses on leadership development. What key message does this book impart to leaders, and how does it tie into your work with executives?
A: I wrote Selbstfindung und Selbstorganisation für Führungskräfte because I observed that many leaders were struggling with the rapid changes of today’s world – especially the digital transformation – and with the classic challenge of “How do I lead others effectively?” In my view, the answer starts with leading yourself. The core message of the book is that effective leadership begins with self-leadership. A leader who hasn’t found their own authentic direction will struggle to guide others. So the book is a step-by-step guide for leaders to work on themselves, to become the best version of who they are. I talk about developing an authentic self-concept: really understanding your own values, strengths, and weaknesses. There’s a chapter about self-organization – essentially self-management – because in the digital age, with information overload and agile work environments, a leader needs to be centered and organized internally to handle external chaos. I also emphasize empathy and values-based leadership throughout the book. It’s full of practical exercises and reflections, from identifying your personal leadership style to improving your work-life balance and emotional resilience.
One important takeaway is that when leaders invest in their own growth, it’s not selfish – it actually multiplies outward. Leaders who cultivate self-awareness, empathy, and clarity end up building stronger teams and healthier organizations. As I say in the book, a leader who knows themselves can inspire and develop others. I incorporate these principles directly into my coaching with executives. For instance, if I’m coaching a manager from London or Dubai, I might assign them a self-reflection exercise from the book – like identifying their core values or writing a personal leadership vision – and then we discuss how that insight can improve how they manage their team. The feedback from readers has been very positive; many appreciate that the book combines psychological insight with concrete leadership advice. In my own practice, it’s almost a framework I stand by: helping people find themselves (Selbstfindung) and organize their lives (Selbstorganisation) so they can lead with confidence, even in challenging, fast-changing environments. When I see one of my coachees apply these ideas – say, by changing how they communicate with their staff and then witnessing better collaboration and productivity – it’s incredibly rewarding. It reinforces why I wrote the book in the first place.
Q: Your other books explore additional themes relevant to psychological and personal development. One of them, Escaping Toxic Ties: Unraveling & Defeating Destructive Relationship Habits, tackles the issue of unhealthy relationships. And your Amazon author page includes several more – such as TOXIC GUILT AND SHAME: THE PRACTICAL WORKBOOK FOR SELF-ACCEPTANCE and LISTEN, THINK, THEN TALK: THE PRACTICAL WORKBOOK FOR BETTER COMMUNICATION. What inspired these works, and how do they reflect your overall mission?
A: These books grew out of real-life needs I saw in my practice. People were suffering – not only from anxiety or burnout, but from complex relational wounds, unprocessed shame, and communication breakdowns. With Escaping Toxic Ties, I wanted to provide an accessible guide for those stuck in emotionally damaging relationships. Toxic Guilt and Shame emerged from my work with individuals who internalized negativity for years and needed structured support in rebuilding their self-worth. Listen, Think, Then Talk focuses on something essential in all human interaction – the ability to truly listen. All these books are my way of reaching an international readership with the same message: you have the right and ability to protect your dignity. They aim to give practical tools – self-reflection, exercises, examples – and to empower people to regain agency. They complement my therapeutic and coaching work because they offer clients an opportunity to continue reflecting between sessions, or even begin the journey before reaching out for help.
