Great Sales Force Partner Network

Hrvoje Ceovic


Hrvoje studied economics and international business at the University of Zagreb and earned his doctorate at WU Vienna. Over a period of almost 30 years, he has gained extensive experience and knowledge through various international leadership and management positions at Procter & Gamble. After retiring from his six-year stint as Vice President Sales in Central Europe, he now wants to share his knowledge with passionate businesses as a consultant. In his private life, Hrvoje produces excellent olive oil, travels the world with his daughters, and shoots a few (basketball) hoops every now and then.


Klaus has a very sporty approach to most topics. This probably comes from the fact that he played handball in his youth and this was his first great passion, which he also pursued professionally. For this reason, he loves challenges and especially facing them as part of a team and overcoming them successfully. Professionally, he was employed for several years in the insurance industry in Austria and Switzerland. He held different management positions in marketing, sales, business development and customer service.


Although he worked for an IT company for almost 20 years, Norbert is the opposite of an IT person. He has had “sales genes” from birth, so to speak, and is at home in the world of (digital) marketing and CRM. Before working as a management consultant and IT service provider, he held various positions as project manager, account manager, sales manager, managing director and business unit manager in an international CRM software company.

Alexander Mayrhofer


Loving his work, Alex indulges in strategic and product challenges where out of the box thinking is crucial. The more this is related to sales issues, the better. In the last 20 years he has gained extensive experience in numerous fields and industries: regional development, hospitality, the financial industry with a focus on insurance sales, public transport, the energy sector, health care, AI and many more. Apart from that? Well… all kinds of outdoor activities and movies, the latter preferably pertaining to science fiction or martial arts (= an all-time hobby). ;-).


Senior Consultant & Trainer

‘Creative and analytical thinking with a sense of what is feasible’ is what distinguishes Christian. As a passionate endurance athlete and trekking fan, he is used to defining goals precisely and planning the way to get there efficiently. In this respect, customer-oriented sales optimisation, both in leadership and at the point of sale, is one of his passions.
Christian draws his expertise from more than 25 years of experience in the areas of sales, marketing, management, human resources and organisational development in a wide variety of positions, from sales representative to managing director, in both national and international environments.

Senior Consultant

“Make complexity simple!” — This guiding principle accompanies Roland in his work as a management consultant, coach and trainer. His expertise is based on more than 20 years of management and leadership experience in international corporate environments and in owner-managed, national companies. In his actions he always pays attention to a good balance between people- and result-orientation. His actions are determined by communication and positive motivation to move people, to accept change and new challenges and to pursue them in a goal-oriented manner.

Senior Consultant

“Turning employee experience data into decisions”: At Great Sales Force, Stefan tirelessly drives the further development of the products and project management of the online surveys in order to be able to offer our customers a fully comprehensive – yet straightforward – consulting/service.

In his private life, Stefan enjoys being out in nature – on foot, on the wave, or on his bike.

Senior Consultant

Dr. Christian Poschik received his doctorate in 1984 from the Vienna University of Economics and Business. This was followed by positions as global vice president, board member and managing director in listed companies such as Henkel, Campofrio Food Group and Agrana Fruit. With 16 years of international experience in both developed and emerging markets (Austria, Germany, Benelux, Czech Republic, Slovakia, Russia), experience in B2C and B2B industries as well as in the management and restructuring of global organizational structures, Christian supports the Great Sales Force® Team with his knowledge as a Senior Consulting Partner since 2017.

Sylvia Walko

Senior Consultant

Sylvia has been involved in the strategic and methodologically sound development of complex corporate brands for 20 years, and this always from the perspective of those who use and appreciate these brands. For her, increasing customer enthusiasm is the ultimate goal, creating service excellence is the crucial foundation and developing the right questions is the never-ending path. She has been walking with GSF® on this path since 2012. Away from consulting, her heart is devoted to coaching, her family, good music, delicious food and yoga.


Together with our partner network, we support companies in implementing measures, improving performance in sales, and thus realising their potential. We work closely with international experts from practice and science to offer our clients and partners the best solutions. Our goal is to scientifically substantiate the practical knowledge of sales and return it to practice.
