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 directors has strengths that complement one another—to the benefit of our clients.
Ilona Groß has been active in management training and business coaching for years. Her greatest strength—in addition to her professional skills—is her open and optimistic disposition. Clients immediately develop trust in her and are able to work very well with her in a short amount of time.
After earning a 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 ten years ago, ultimately earning her certification as an IHK Business Coach. Since the founding of Groß & Cie., she has also overseen 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 encapsulates her coaching philosophy: “The Best Is Yet to Come! How to Gain New Energy for Our Lives.”
Taking on new challenges and consistently pursuing goals is Michael Groß’s professional motto—a mindset shaped in part by his former “side activity,” competitive swimming. It was therefore a natural step for him to launch his own practice as a management consultant after earning his Dr. phil. degree and to continuously develop his skills.
At Groß & Cie., he draws not only on his diverse experience gained through hundreds of different client projects. He also 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. He is also a curator of the Sports Management MBA program at the Goethe Business School. He further shares his knowledge through management books. In 2013, the reference book "Self-Coaching", 2014 the "Change Manager Handbook" and in 2018, the "Digital Leader Gamebook".
