In recent years I have specialized most in depression and negative self-images and how they work on a cellular level. Depression can have a variety of causes, including diet, medication, illness, and emotional setbacks. The mind, or in other words your mindset, can make your body unhealthy and thereby provoke inflammatory depression. It also works the other way around, depression or inflammation in the body cause negative thinking. You can use my knowledge and services to escape from the negative spiral of depression. At the moment I am attending lectures on the combination of behaviour, biology and evolution. This shows that a lot of our behavior goes beyond our own lives. I apply this new knowledge to new sessions.

Prep call
I had a wonderful preparation call with Marcel. He knows all the ins and outs of psilocybin and how it works in the brain. By explaining he took away all the fear that I had to make the next step.
