TentaConsult takes off with a well-known face and relevant market experience – Ralf G. Sibbing


TentaConsult Pharma & Med GmbH starts in Münster with a well-known head from the industry with almost two and a half decades of experience and a profound knowledge of pharmaceuticals and medical devices in almost all consulting and service areas.

Ralf Sibbing, a specialized pharmacist and pharmacist by training, brings with him many years of experience in pharmaceutical consulting and regulatory affairs. In his more than 20 years of working for a management consultancy in Münster, Ralf Sibbing successfully assumed various consulting, managerial and executive roles. Among other things, he was responsible for the development and expansion of the quality services division as well as for the internationalisation in China, Austria and BeNeLux. In his last position as Managing Partner, Mr. Sibbing was responsible for the sales area of the entire group of companies.

With a powerful team of experienced consultants and senior consultants in TentaConsult, complemented by the consultants and scientists of the Tentamus Group with its international network of highly specialized laboratories in the testing area worldwide, TentaConsult is now starting the joint path with Tentamus and thus offers an even broader range of services for all customers. TentaConsult will provide its customers in the fields of pharmaceuticals, medical devices and dietary supplements with advice and support. In the interest of its customers, TentaConsult will also bundle the immense expertise already united in the Tentamus Group and make it transparent to the customer.

Contact us, we will develop individual solution concepts together with you and offer a wide range of services – not only to relieve your teams of capacity, but also to give you the opportunity to concentrate your energies entirely on your core competencies. Just as you wish and just as you need it at the moment.
