LOCATIONS

Ottobock worldwide

Information on Ottobock’s subsidiaries worldwide and our global Patient Care clinics can be found here.

Global presence

A global reach – close to people

Latin America

In Brazil since 1975

For over 40 years, Ottobock has been developing the markets in this region – some of which have very diverse cultures. Dedication and determination are important motivating forces here. Our goal is to use our expertise, commitment and outstanding products so we can deliver end-to-end solutions, in particular to create more opportunities for social integration.

North America

In the US since 1958

The US is medical technology’s strongest national market. Given this, Ottobock’s work in North America focuses on investments in technology, collaboration with renowned research institutions and strategic partnerships with customers. Ottobock USA was the first foreign branch founded by the company, later followed by Canada.

Western Europe

In Germany since 1919

Dedicated employees in our research and development centres in Western Europe ensure our company remains the leader in technology for our market – quality for life for people with limited mobility. Involving key thinkers from the region makes it possible to quickly identify and meet local market requirements.

Eastern Europe, Middle East, Africa

In Croatia since 1995

Inspired and motivated by cultural diversity, the different business environments and incredible potential of the EEMEA region, Ottobock works closely with various interest groups to offer the best possible treatment standards and outstanding service for patients and business partners alike.

Asia Pacific

In Australia since 1974

More than 40 Patient Care clinics in the Asia Pacific region keep us close to our customers and patients. They make it possible for many people in this region to benefit from high treatment standards and regain their own maximum level of mobility.
