A partnership requires trust.
We’ve had that for over 25 years.
Are you wondering who is Groß and who is Cie.?
In our partnership, we work as equals. Each of the managing partners has their own strengths, which complement one another—to the benefit of our clients.
Ilona Groß has been active in management training and business coaching for many years. In addition to her professional expertise, her greatest strength is her open and optimistic nature. Clients immediately develop trust in her and are able to work very well with her in a short period of time.
After completing her degree in business administration, she worked for over a decade as a department head and authorized signatory at two tourism companies. Through the planning and execution of conferences, specialized study tours, and seminars, she developed a deep connection to the field of training and coaching over a decade ago, eventually earning her certification as an IHK Business Coach. Since the founding of Groß & Cie., she has also managed the events division, including large kick-off events with over 1,000 participants. She finds relaxation in her side job as a fitness trainer.
In 2020, she published her first book together with her partner Michael. The title also serves as a guiding principle for her coaching: “The Best Is Yet to Come! How We Gain New Energy for Our Lives.”
Embracing new challenges and consistently pursuing goals is Michael Groß’s professional motto—a mindset shaped in part by his former “side hobby,” competitive swimming. It was therefore a natural step for him to launch his own business as a management consultant after earning his Ph.D. and to continuously develop his skills.
At Groß & Cie., he draws not only on his diverse experience from hundreds of different client projects. He collaborates closely with the “Center for Leadership and Behavior in Organizations” at Goethe University Frankfurt am Main. Since 2023, he has served as an honorary professor of organization and leadership in the digital age in the Department of Economics there. Among other things, he teaches in the master’s seminar “ Digital Leadership ". He also shares his knowledge in management books. In 2013, the reference book was published “Self-coaching”, 2014 the "The Change Manager's Handbook" and in 2018 the “Digital Leader Gamebook”.
