After completing his studies at Vienna University of Economics and Business Administration, Guido Leissinger began his professional career in management consultancy. His successful activities included organisational consultancy in many different companies dealing in a variety of commercial fields. Due to his very distinct interest in people, he switched from management to personnel consultancy.
Guido Leissinger founded ISG in 1999 and has since built up the company from zero to more than 500 people in 23 countries.
His leadership style is characterised by the notion that the human being should always be the central focus of all considerations. ISG’s long-term success can only be achieved through teamwork, mutual respect and understanding as well as constant on-the-job training.
Motto: „Success is not a coincidence“
