Different Concepts - Better Results

The Human Development Company (THDC) is on the cutting edge of developing human potential. Our original concepts are generating excited discussions about the effectiveness of our new  tools and modalities. We know the importance that awareness, vision, and communication play in personal development and relationships. By knowing the most effective ways to develop each, combining them with loving behaviors given unconditionally, and integrating these four facilities sequentially, can the effective development and full self-actualization of human beings be realized.


This is what Dr. Roberta Karant, Director of Education for THDC says;

“I heard Stefan Deutsch give a talk about his ideas five and a half years ago and my first reaction was, ‘Wow. I had never heard concepts on human development, psychotherapy or love that were comparable. Simple, intuitive, experiential, logical – but most of all – they rang true. I thought this is someone I have to work with – he is going to change the world.’ A lot of people are called Foremost Experts in this or that field. I don’t believe it applies to anyone more than Stefan as far as the realms of love, loving, healing or developing human potential are concerned. I’ve been working with Stefan Deutsch ever since, and have witnessed the power of his ideas in our work as well as in my own practice and life firsthand.“



We got the model that works....and you're welcome to it.

Take a close look at our ideas and concepts and learn about the differences between our approach to parenting, relationships, marriage, aging, health, success and other mainstream ideas. The good news is that we have tested our ideas over the past 15 years and they work.
