Leading Simple Seminars

"Boris Grundl and his team don't sugarcoat anything and really move you forward. The seminar had a lot of depth. "

Gerald Kneissle

"The special feature of the seminar is the depth, the directness, the high tempo. It is about "doing it yourself". It is insightful and emotional - and therefore valuable. You "only" have to be 110% committed to it."

Tanja Schirmer

"I am impressed with the depth of the overall content, the clarity and precision of the exercises and reminders, and how straightforward the underlying approach is."






Stefanie Ulrich

„Mr. Grundl is an outstanding expert on issues of employee management. Anyone who masters his life so successfully despite such a difficult fate is an ideal speaker for this field. Anyone who has experienced him live knows that he lives exactly what he talks about."

„Boris Grundl says what is important: transparent, comprehensible, authentic! His impulses, presented with great passion, offer an exciting fund of methods for leading people.“

Dr. Marcos Arias,

Head of International Sales, IVF HARTMANN AG

"Boris Grundl's leadership seminar is an experience. Sustainable, practice-oriented, and authentic, Boris Grundl conveys simple but meaningful content to the seminar participants. His persuasiveness is fascinating, as Boris Grundl "lives" his clear and precise messages. In his seminars the participant feels the conveyed contents are practice, not only theory. Learning about people management from Boris Grundl also means dealing intensively with oneself and clearly defining one's goals. For me, the terms "result", "success", "discipline" and "self-motivation" have taken on a new intensity.

Boris Grundl has a fascinating knowledge of human nature. This and his experience with processing and overcoming a serious accident that completely changed his life make him a convincing and authentic coach. The person Boris Grundl is straightforward, disciplined, direct and has an incredible energy - he captivates his audience from the very first second. Boris Grundl provokes and asks many questions - the result are answers."

"I am extremely happy and grateful that Leading Simple exists and that I was able to get to know this system. I thank you for the valuable feedback during my implementation reports and the interesting implementation discussions during which I could always gain new insights. The intervals of the conversations come at exactly the right time and have the appropriate content! Thanks to Leading Simple, I was able to introduce a new spirit, a new way of dealing with people, a new leadership style in my company. And if anyone thinks that Leading Simple is not measurable, they are definitely wrong. All my employees who work with Leading Simple are convinced of the system and are grateful that the company invests so wisely in employee development and appreciate being part of it."

Michael Imhof

"Boris Grundl has earned our respect with the way he deals with the consequences of his accident. Beyond that, however, he knows how to inspire, to dispel myths about leadership, and to clearly convey what leadership really is. It is the combination of three components that makes Boris Grundl so effective: respect for his life's work, his expertise and his ability to raise the leadership behavior of his seminar participants to a much higher level."

Alexandra Heine,

"As a coach, Mr. Grundl leads one unflinchingly without detour to personal weaknesses. He consistently and purposefully reaches the starting point of elementary changes with a high degree of effectiveness. He gives you no chance to avoid a confrontation with yourself. At the same time, you clearly feel that he understands the difficulty you are struggling with very well and thus mobilizes your own will to change. In doing so, he manages to walk the tightrope between challenge and respect for personal individuality in a wonderful way."
