As an employee from the very beginning, Janet Reinhold has had a significant influence on our corporate culture. She worked closely with Dr Dirk-Reiner Martens for more than 20 years and played a key role in the founding of our firm.

Having previously worked for many years in an international commercial law firm, Janet is very familiar with the competent administrative support of international projects, extensive due diligence mandates and arbitration proceedings. There, she also headed up the in-house training team. As part of this role, she supported the programming and enhancement of the firm’s proprietary lawyer software, developed comprehensive training plans and user manuals, and was responsible for the rollout of the software as well as for the training courses in Germany and abroad.

As office manager of our law firm, Janet keeps all the threads of the office organisation together. She is the first point of contact for our lawyers and clients in all organisational matters. As an impulse generator and project manager, she is also tirelessly committed to the further development and successful implementation of internal and client-related projects. This includes, in particular, the organisation and support of internal and external events, such as the BAT User Conference, as well as the further development and implementation of our IT.

In addition, Janet has extensive experience in the administration of dispute resolution mechanisms. Since 1998 she has been coordinating the FIBA Appeals’ Panel.  Furthermore, she has been instrumental in the development and continuous expansion of the administrative and technical concept of two institutional arbitration tribunals developed and administered by our law firm: the Basketball Arbitral Tribunal (BAT) and the Court of Innovative Arbitration (COIA).
