Karla Medrano Cebrian
Founder and Co-Director of DermaMedicum
Specialist in dermatology and venereology
Additional qualification in allergology
I'm originally from Panama City and have been living in Germany since 2017. I completed my medical studies in Monterrey, Mexico and was able to gain medical experience in various countries during my training — including Mexico, Panama, the United Kingdom, Spain and Germany.
I completed my specialist training in dermatology in Bonn, together with Ariana Palacio. This intensive period not only gave rise to a close friendship, but also the desire to establish a modern, internationally oriented practice. Today, we are fulfilling this dream in Bonn, our new home.
For me, dermatology combines precise diagnostics, innovative technology, and personalized patient care. I am particularly interested in dermato-oncology, dermatosurgery, aesthetic dermatology, laser treatments and allergology.

Founder and Co-Director of DermaMedicum
Specialist in dermatology and venereology
Additional qualification: drug-based tumor therapy
Additional qualification in allergology
I come from Barcelona and have been living in Germany since 2018.
Even during my medical studies, I was drawn to faraway places: internships took me to California, Italy, and Austria. So it's no surprise that after graduation, I was eager for a new adventure and came to Bonn for my further training in dermatology.
I completed my residency there alongside Karla Medrano Cebrian. Our friendship has grown over the years, and now we're fulfilling our dream together: our own practice in our new home.
My interest in dermatology arose from the diverse treatment options, the personal and trusting patient contact and the promising future of new treatment methods and advances in medical research. I am particularly fascinated by dermato-oncology, surgery, laser therapy, pediatric dermatology and hair medicine.

Marika Melis
Medical assistant
From Italy to Germany. Buongiorno, Bonn!
I discovered dermatology at the age of 19 and have been hooked ever since. I love aesthetics and structure just as much as sports and good conversation. Order in my head, passion in my heart, and always a touch of la dolce vita.
Sempre con il sorriso – always with a smile.

Medical assistant
I was born in Bonn and have Moroccan roots.
After completing my training as a medical assistant, I have now been working in dermatology for over 14 years. I particularly enjoy the close contact with our patients and the variety of dermatological activities in everyday practice.
In my free time, I enjoy walks in nature and relaxing with a good book.
