Jan Stritzke studied medicine at the Christian-Albrechts University in Kiel. He completed his specialist training at the University Hospital Schleswig-Holstein, Lübeck Campus. Under the clinical supervision of Prof. Dr. Heribert Schunkert, he discovered his passion for preventive cardiology and non-invasive imaging at an early age. His scientific interest was particularly in the effects of obesity and high blood pressure on cardiovascular aging. This work led to several scientific publications.

After training as a specialist in internal medicine and cardiology, he specialized further in preventive cardiology. It was only logical for him to pursue this passion at the Lanserhof. He initially worked for six years as deputy medical director at the Lanserhof Tegernsee before finally being appointed founding director of the Lanserhof on the island of Sylt.
