After that she worked at the Dermatology Unit of the University of Jena leading their Dermpath Lab before she changed to a Dermatology practice in Kempen where she finished her specialty training.
During her maternal break she picked up her MPH studies at the University of Düsseldorf and started to work as a Dermatology consultant in a busy Gynecology practice in Bruchsal and continued to broaden her knowledge of Traditional Chinese Medicine at the University Witten-Herdecke.
In 2009, after returning from Norway, where she spent two years with her family during a sabattical, she started to work in Ratingen/Lintorf, building her Dermatology practice as you see it today.
