About us
OÄ Dr.in Asha Leisser, MBA
Specialist in nuclear medicine, General practitioner
“Between books, people and countries, I have learned that healing requires more than just knowledge.”
After my graduation in 2012 from the Medical University of Vienna, I completed my specialist training in nuclear medicine at Vienna General Hospital (AKH Vienna). In addition to my clinical work, I was active in research and teaching—focusing on new radiopharmaceuticals for nuclear medicine imaging and therapy. A research year took me to Cleveland, Ohio (USA).
I subsequently completed training as a general practitioner. At Klinik Ottakring, I coordinated nuclear medicine therapies and deepened my expertise as a private physician in the Thyroid Center Vienna.
Since 2024 I have been a senior physician at Klinik Donaustadt, where I head the nuclear medicine laboratory—focusing on thyroid and bone metabolism parameters for our outpatient clinic as well as the entire hospital.
Precise diagnostics, individualized counseling and respectful interaction are at the heart of my work—for a kind of medicine that not only treats, but accompanies.
Dr. Thomas Nakuz
Specialist in nuclear medicine
“At 14 I gave a talk on nuclear medicine—without realizing that I had already found my calling.”
I completed my training as a specialist in nuclear medicine at AKH Vienna. There I not only received comprehensive training and gained a wealth of practical experience, but also met my wife.
Today I head neuro‑nuclear medicine at AKH and previously led the scintigraphy outpatient clinic. I am also involved in teaching—both for medical students and for radiologic technologists, which is especially important to me.
In working with patients, I place great value on respectful communication. I try to explain medical contexts in an understandable way, because I am convinced that those who understand what is happening in their bodies, feel less fear and more in control.
