Hi! I’m Katharina Seidler

Licensed Psychologist, Therapist and Trainer

Although I’m a classically trained psychologist, my journey has led me to explore many other types of therapy and healing, and my approach is a fusion of many of these. My clients come from all over the world and all walks of life. But whether stars of stage or screen or stay-at-home moms, they all share the same vision. To become the person they truly are, to feel peaceful, empowered  and to grow a little more every day. To be better and more fulfilled in their careers, and their relationships; ultimately to get more out of life. If you’ve been looking for something more, you might just have found it.

Are you ready to change your life?

The Power of Transformation

We all have occasional issues with our lives – our careers, our relationships, our general sense of well-being. But if these feelings become more than occasional, it can affect all aspects of our life, and can easily damage careers and relationships. ReSource Yourself teaches you how to apply specific Energy Psychology tools to release old baggage, change your mindset and transform your life experience – from the inside out!

Our Products and Courses

The Personal Power Test is a free, online test which shows you how negative feelings and emotions may be holding you back – in both your public and personal life.

The test uses current consciousness level theory to generate a personalised report, which is then sent to you by email after the test has finished. The PPT itself is a great way of finding out more about yourself – it only takes a couple of minutes.

Get Positive! is a 5-day audio mini-course helping you to overcome negative feelings and emotions that may be holding you back.

With all modules completely downloadable, Get Positive is designed to be with you, wherever you are. And with an efficient combination of audio/reading and self-study, you will start feeling improvements almost immediately.

The Power of You is our flagship 10 week course designed quite simply to help you reach the real you and become the person you deserve to be.

The course uses video seminars as well as live webinars and one-to-one direct support via Skype. The number of participants is strictly limited and courses run about 4 times a year.

My Approach

Initially, I studied classical psychology and worked for a psychological consultancy. In parallel, I absorbed any alternative form and method of healing that came my way. Over and over I reached professional limits – but I learned to overcome them and to go further than even I might have thought it possible 15 years ago.

Meanwhile, I have developed the ReSource Yourself Method, integrating the world of science and psychology with that of spiritual growth and healing. It is based on my training and experience with NLP, Reiki, EFT/Tapping, Body Code, Ho’oponopono, Mirror Work, Kinesiology and Reconnective Healing.

I am very pragmatic: If it works and if it brings results, it’s good. It’s important for me to empower my clients and to show them how they can use the tools and approaches by themselves. After all, real power comes from knowing that everything you need is within yourself.

Emily, aged 26

With ReSource Yourself, I have reached freedom. The other day, we watched a movie and my sister asked me what “my word” was for myself. I answered “freedom” and then I realized, that is what I feel now. In just three sessions, the things I was worrying about just lifted! And I feel so much… Read more “Emily, aged 26”

Emily, aged 43

I‘ve had a lot less fear and anxiety. When I do feel anxiety, now I got tools for not resisting it, and that makes it much less!

Emily, aged 44

Kat is probably the most compassionate, supportive and insightful person I have ever worked with. I made leaps and bounds of progress through working with her, and I can’t sing her enough praises. She’s got a gift that is absolutely transformative!

Johanna, aged 37

I deal with situations now that were always a challenge for me in a completely different way. Now I face them, and they aren’t a challenge anymore.

Lars, aged 38

Katharina has a great gift in breaking down walls where you thought there were none. She provides a safe place to talk about perceived shortcomings, opportunities for growth, fears, aspirations and the relationship to self and others. Are you ready to level up?

Susanne, aged 60

Katharina is a very skilled and empathetic person, with the warmth of her heart she guided me serval times, when the river of my life became wild and strange and rough. It does take courage, but almost no time till the first tiny changes show up. (And the steam of change is carrying on for… Read more “Susanne, aged 60”

Marta, aged 30

For the first time in my life, I had decided I needed to do coaching and consult with an expert about the path my life had taken and how to make things work in a different way. After giving it a lot of thought I decided that Katharina would be the person to help me… Read more “Marta, aged 30”


She has a way of finding the core of a problem and solving it. Highly recommended!

Tuula, aged 52

Katharina gets to the root of the problem quickly, and the sessions are efficient and very different each time! Highly recommended to anyone who wants to accelerate their growth and step into their power!

Edeltraud, aged 62

I simply felt better: Right after the first appointment I had the feeling of emerging from a deep valley. That almost immediately gave me the experience to be more active again and to be able to act, not just react. In the process, Kat has given me the confidence that I would feel better again.… Read more “Edeltraud, aged 62”

Hendrik, aged 34

What a journey! I have never done this before but I’m so thankful that I did. I’m also very thankful for a very special person of mine who inspired and introduced me to Kat and her methods and gave me the support that I needed. I’ve often felt that I got stuck in some situations,… Read more “Hendrik, aged 34”

Nuria, aged 42

Thanks to Kat and despite my initial skepticism, I’ve gotten to heal things that seemed impossible to overcome – in a very short time. This is not therapy, it is magic … and healing power. Thanks, Kat, for your dedication, your enthusiasm and love with which you do your job

Xin, aged 37

You let me see a different world – one I was dreaming of. I didn’t realize I can really reach it and be it. It’s amazing. Life goes on – and it will be more beautiful!

Sarah, aged 33

When I came to see Katharina, I really didn’t have a big problem, but I was dissatisfied – with myself, my work, my environment. I thought that everybody else had it better, and I was envious of the my friends’ and my partner’s success. Today, 9 months later, things have changed … for the better!Read more “Sarah, aged 33”

Maria-Dolores, aged 37

I’ve managed to heal my relationship with money and my work. Also some aspects of myself in relationships with others: my partner, my parents – and I can apply this to any other relationship. When I only think of Kat, my heart opens and warmth comes out, and now I can say – that is… Read more “Maria-Dolores, aged 37”

Jasmin, aged 33

Katharina helped me in addition to the classical approach with her empathy and alternative methods not only to cope with my anxiety, to deal with the death of my father, which I managed to suppress since I was a child, but also to understand how I actually perceive myself and learn to accept myself as I am.
