Career
In 1989, Mronz organised his first tennis tournament, the Pohland Cup in Cologne, then later the Cologne Open. Michael Mronz e.K. was founded by Mronz in 1992 as MM Promotion Michael Mronz and was renamed Michael Mronz e.K. in November 2016. The focal point of the events that he organises are sports events such as marathons, equestrian, tennis, beach volleyball and hockey tournaments.

Mronz has been the General Manager of the Aachener Reitturnier GmbH since October 1, 1997, which is responsible for the marketing of the CHIO Aachen, the largest equestrian event in the world. Based on the competences he acquired in this position, Mronz was also appointed Head of the Organising Committee of the World Equestrian Games in 2006, the second largest sporting event in Germany after the Football World Cup that was staged in the same year. For the first time since the Equestrian and Driving World Championships were founded in 1990, this event succeeded in closing on a positive net result. After the great success of the FEI World Equestrian Games, the trade magazine “Horizont” elected Michael Mronz as “Sports Manager of the Year”. In his capacity as Marketing Director, Mronz was responsible for the marketing and ticketing of the World Athletics Championships in 2009 in Berlin. In 2002, Mronz became a member of the board of the Hanne-Nüsslein Foundation of the KTHC Red-White stadium. The foundation has set itself the aim of promoting young tennis talents. Up until December 2003, he was shareholder and Managing Director of the American Sports GmbH, under the umbrella of which the first ladies’ and the first men’s team of the German basketball league club, RheinEnergie Cologne, fall. He stepped down due to differences of opinion concerning the future alignment of the organisation’s structure.

Since 2013, he has been the organiser of the famous ATP tournament, BMW Open by FWU AG, in Munich. He advises the organisers of the German racing series DTM and of the 2018 European Athletics Championships in Berlin. Mronz is the initiator and organiser of the “Rhine-Ruhr Olympic City 2028” initiative that is backed by the private sector. This idea of the Rhine-Ruhr region putting in a bid to stage the 2028 Summer Olympics is being met with great enthusiasm from economic and political circles. Mronz has developed a concept that relies upon sustainability and the usage of existing sports and event facilities. Michael Mronz took over the Chair of the Westerwelle Foundation in 2016, which asserts itself on an international basis for democracy, the rule of law, the social market economy, and political and economic participation.
