About us

Raphael Jung

Conception & Founder

Raphael is a trained sports scientist and the founder of Diagnose Berlin. In the years prior he was active in sport science and metabolic research. In addition to various student projects in neurology and biomechanics, he led his own research project on skeletal-muscle cells and their adaptive responses to various training stimuli. During this time he completed internships at the finest performance diagnostics institutions in Germany. Often disappointed by the lack of depth in planning and implementing performance tests, he went on to meticulously develop the services now offered at Diagnose Berlin.
