concept of Practice
The sick and the healthy child and their parents with their worries, needs and questions but also with their feelings of happiness are the focus of our thoughts, feelings and actions.
We treat your child gently and sensitively, without being hesitant.
We demonstrate understanding, tolerance and empathy for our patients and are open to your individual needs and the needs of your family.
We listen and act with the necessary calm and competence, always on the basis of current medical studies and recommendations from specialist committees. We are uncompromising when it comes to the health and well-being of your children and avoid unnecessary examinations and therapies.
We demonstrate understanding, tolerance and empathy for our patients and are open to your individual needs and the needs of your family.
Two pediatricians and one psychologist work in the same direction, but in addition to different focuses, we also allow ourselves differences in the practice of our “medical art”.
