About Us

In 1982 in South Africa, PresMed Investments was founded by Carl Grillenberger when he established a number of small multi-disciplinary day hospital facilities. Three years later PresMed was listed on the Johannesburg Stock Exchange and grew into the top 5 hospital and day surgery groups in the country.

PresMed later then merged its business with the Lifecare Clinics Hospital Group headed by Managing Director Marc Resnik, to become one the major hospital groups in the country in 1996.  This business was eventually sold to another healthcare group.

A decision was then made to set up a separate independent company in Australia, and in 1997 Presmed Australia was established in Sydney.

Presmed specialises in the investment, commissioning and management of day hospital facilities in partnership with surgeons, and has established 5 major facilities in Chatswood, Epping, the Central Coast, Hornsby and Coffs Harbour, with more than 120 accredited surgeons associated with the day hospitals.
