Portrait von Katja Kassem-Trautmann im Arztkittel

Katja Kassem-Trautmann

My highly developed sense of aesthetic harmony and my unusually broad range of surgical experience and training strengthen my work as a plastic surgeon, especially when it comes to cosmetic procedures. I value honesty in consultation, and I believe that perfection means something different for each body, which is why I emphasize individually tailored results using individually tailored approaches. I draw upon modern treatment concepts developed by internationally renowned colleagues while also creating and using new techniques of my own, working in close cooperation with clinics in Brussels, Beirut, Paris, Lyon, Miami, São Paulo and Munich.

About me

I have known ever since I was a small child that I wanted to pursue a career in medicine. Growing up in a war zone meant that I encountered injuries and health care early on as well; the medical professionals working in my home country on behalf of Doctors Without Borders became my role models. By the age of four, I wanted to become a doctor when I grew up. At age six, having seen the many burn victims in my war-torn surroundings, I set a more concrete goal: I decided to become a plastic surgeon. It was around that same time that I began drawing people, focusing on their insides: I sketched organs and structures, discussing their shape and function with my grandfather, an Arab physician. My curiosity and thirst for knowledge grew and grew.

I began studying medicine at the University of Münster in 2002, earning my medical degree in 2008. One of the several medical residencies I completed in the years that followed took me to the University Hospital of Zurich, where I worked in emergency medicine, polytrauma, vascular surgery, and cardiac surgery; I also spent time in the pediatric cardiac surgery department at the University Children’s Hospital. Yet cosmetic and reconstructive surgery still held a special place in my heart, so I pursued specialty certification in that field, and became an FMH-certified Specialist in Plastic, Aesthetic and Reconstructive Surgery in 2017.

I opened my own clinic in Zug in 2019. Since then, I have been offering my patients a broad spectrum of cosmetic and reconstructive treatments, including conventional surgical procedures, body contouring, liposuction, breast enlargement, and modern minimally invasive and non-surgical treatments such as thread lifts, fillers, Botox®, PRP therapy, autologous fat transplantation (lipofilling), and laser treatments. Since I share a group practice with a pair of dermatologists (Hautpraxis Zug), tumor surgery is another primary pillar of my medical work. Given the interdisciplinary nature of my field, collaboration with colleagues in other medical disciplines (e.g., visceral surgeons) serves as the basis for an enormous range of treatment options.

I completed all of my medical training in Germany and Switzerland, learning and working alongside renowned specialists like Prof. Dr. med. René Prêtre and Prof. Dr. Steffen Baumeister. Close cooperation with colleagues, mentors, and friends like Prof. Prêtre and Prof. Dr. Gottfried Lemperle remains extremely important to me—not only from the scientific and surgical standpoints, but on a personal level as well.

More about my career

  • My path to becoming a plastic surgeon

    After medical school, I started out in cardiac and vascular surgery, because I wanted to gain a more precise understanding of human blood vessels and methods of stopping bleeding; this also helped me master delicate surgical technique. My subsequent work in pediatric cardiac surgery taught me to operate with extreme precision, to respect highly sensitive tissue and handle it accordingly. After that, I worked in trauma surgery, completing a residency in emergency and polytrauma care. My personal goal was to treat injuries and complications while reconstructing patients‘ natural appearance. In 2017, I completed my (FMH) specialist certification as a Doctor of Aesthetic, Plastic, and Reconstructive Surgery. I then worked as a Senior Consultant in Plastic, Hand, and Aesthetic Surgery at Schwarzwald-Baar Hospital in Donaueschingen, a teaching hospital run by the University of Freiburg im Breisgau. Additional training and certification at the national and international levels followed, particularly in body contouring and lipomodeling using autologous fat; these remain an important component of my day-to-day work.

  • Medicine, aesthetics, and art

    Combining and integrating medicine, aesthetics, and art has always been essential to me and my work, which was why I took a semester of art (multimedia graduate studies) at the Enschede (NL) Academy of Art and Industry before enrolling in medical school at the University of Münster. While there, I spent five years as a graduate assistant to the Anatomy department, preparing slides and teaching classes. I also taught myself to do medical illustrations. Before drawing anything in detail, I insisted on viewing the organ or structure up close while observing an operation; this was an excellent opportunity to witness new surgical techniques first-hand and gain in-depth insight into the particularities of the human physique.

  • Continuing education is the key to excellence

    Learning never stops… especially for surgeons!

    I personally place great importance on lifelong learning, because I want to keep offering my patients state-of-the-art treatment at all times. This is also part of the reason that I regularly attend national and international conferences, often as a presenter. I have held visiting-physician posts in France and America, among other places, and I have published several books in cooperation with other medical specialists. I maintain regular contact with colleagues across the globe (in Beirut (Lebanon), Brazil, the UAE, France, and Miami (US), to name but a few).

  • Civic involvement and labors of love

    I have always enjoyed using my great passion for medicine in service to society. My years of charitable work in the Democratic Republic of Congo as an active member of INTERPLAST Germany e.V. have had an especially strong influence on me from both personal and professional standpoints. Through these endeavors, I have gathered a wealth of knowledge and experience as comprehensive as it is unusual, especially in the field of scar treatment. Since 2006, I have also served as the founder and head of Liberi pacifer e.V., an aid organization for children in war and crisis zones.
