In the last six years, through her company, Masakhane Strategic Health Consulting (Pty) Ltd, Vanessa has consulted widely to diverse clients (including the United Nations Office on Drugs and Crime, and the Minerals Council South Africa), bringing-cutting edge knowledge to inform policy, strategy, leadership behaviours, and clinical standards for the prevention, early diagnosis, and compensation of occupational diseases. She is passionate about driving health strategy beyond legislative compliance, and ending smoking AND occupational lung diseases - the latter bringing untold suffering to mineworkers, their families and the public health system.

 Vanessa has also contributed extensively to debates on compensation legislation and strongly believes that through her work we can uphold the dignity of workers.

 She believes that education is a lifelong journey of joy and that medicine should be practised with “science, art and heart”, meaning that, while scientific evidence informs our decisions, we have to constantly apply ourselves in the real world by joining all the dots (art)  and placing the patient at the centre within the full context of the psychosocial-political situation (heart).
