Over 75 professional victories, including 4 Arnold Classic titles, 185 top 3 placements in the IFBB Pro League, including 5 Arnold Classic 2nd places, 4 3rd places at the Olympia, and 8 3rd places at the Arnolds speak for themselves. Athletes such as Urs Kalecinski, Martin Fitzwater, William Bonac, Wesley Vissers, Andrea Mammoli, Andrei Dieu, Diogo Montenegro, Jeanne Kassel, Nadine Huber, Alexis Drury, and many more have trusted Stefan's objectivity and long-term planning for years.
