Who We Are – 123sonography Team

We are a team of cardiologists from the Medical University of Vienna / Austria, and we have strong ties to other national and international institutions, hospitals and experts.


Thomas Binder, MD

"Give me an echo machine! I am lost without one."

Thomas, a.k.a. "Tommy", is professor at the Medical University of Vienna and heads the echo lab   there. Tommy has over 20 years of echo experience. In addition to his scientific work that deals with   topics such as 3D echocardiography, cardiac resynchronization therapy, speckle tracking and clinical research, he has been a dedicated teacher for many years. Over the years, he has seen what works in practice and he uses his practical experience and hands-on approach in teaching.


Georg Goliasch, MD, PhD

"It’s done."

Georg has been with us from the start, when he was still a medical student. Within no time he received his MD and completed his PhD in Vascular Biology. Georg has already published numerous articles in renowned medical journals and completed a research fellowship in cardiovascular imaging at the Mount Sinai Hospital (New York, US). Most of the teaching material that you will see in our courses has been optimized, proof-read and tweaked by him. He’s the ‘sine qua non’ of 123sonography.

Oliver Hübler

"No problem, it can be done."

Oliver is our tech wizard, the master of the visible and the invisible. He has created our online   infrastructure and is the architect of your user experience. Tell him what you want - he has a solution. Oliver has a real interest in medicine, which makes him an ideal team partner. He has an education in computer technology and a bachelor’s degree in the science of web design and   development. Thanks to Oliver, technical things are running smoothly at 123sonography.

Saskia Erbschwendner

"Just do it!"

Saskia is the heart and soul of 123sonography. Upon completion of her studies in communication sciences and gaining some work experience in the field of public relations, she joined the 123sonography team to support a great idea with passion. Saskia  is our chief operating officer and takes care of all the administrative things; she pulls the strings behind the scene and  makes you feel at home. Even though she is based in the Austrian city of Salzburg, Saskia seems to live in a "different" time zone. She is a real night owl, so don’t be surprised if you are from the other side of the "pond" and receive an email from her without delay.

Mag. Sujata Wagner

Sujata joined our team when we realized that learning works best when videos are complemented by written information. Sujata edits our newsletter, polishes our e-book entries, and makes them easy to understand. Sujata was born in India, where she studied history and German. She has worked as a medical translator and in medical journalism for several years.
