As a well established practice, OSA surgeons have supported patients through every stage of their surgical journey. We combine extensive clinical expertise with a patient-first approach, ensuring every individual feels informed, supported, and confident in their care.

We believe high-quality surgical care should be accessible to everyone, regardless of postcode. That’s why we consult and operate not only in Dunedin, but also regularly in Oamaru, Balclutha, and Wanaka, improving access to specialist care throughout Otago.
