“Everything I do, I am dedicated to help people on their journey to wellbeing. I help people to heal their gut. I believe that our physical and mental health is affected by our gut health, making the gut an essential point of healing, especially in chronic disease. I also believe in the power of knowledge and education. The way I help people is by educating and by bridging the gap between conventional and non-conventional healthcare so people can make informed choices. I apply the principles of Functional Medicine to make people healthier.” Dr. Joanna from Amsterdm, the Netherlands
