Bridging the gap between Medicine & the Law
Mr Thomas Kossmann, an international orthopaedic surgeon founded Lex Medicus, together with Associate Professor Cristina Morganti-Kossmann and their daughter Giulia Kossmann, after becoming interested in medico-legal matters and medicine. This is where our slogan ‘Bridging the gap between Medicine & the Law’ was born.
What sets us apart is our unique beginning – founded by a doctor and a scientist. This distinctive blend of medical insight and scientific rigour forms the foundation of our success. Recognising a distinct gap in the market, we have become renowned for the exceptional quality of our reports, the depth of medical expertise and long-lasting partnerships.
Over time, our family has expanded, and we now proudly stand alongside 30+ talented professionals.
We've diligently cultivated strong operational foundations, forged enduring partnerships, and crafted a reputation we're truly proud of.
Lex Medicus is privileged to collaborate with over 220+ experienced and credentialed medical experts, spanning over 50 specialties. Together, we are committed to delivering impartial, fit-for-purpose and high-quality medico-legal reports and impairment services throughout Australia.
Our objective has always been to invest in our amazing team of people, harnessing the incredible depth of knowledge and experience, but also to create an inclusive culture built on family values.
