Meet the team

A dynamic and talented team, driven by positive health outcomes for all of our patients.

The Founders

Peter Slattery
Co-founder and Director

Peter is a co-founder of Proact Health and responsible for the commercial aspects of our business.

Following a long career in the legal profession as both a commercial lawyer and the CEO of a major national law firm, Peter’s interest in preventative healthcare and the challenges many people face in gaining access to high quality primary care services led to a collaboration with Dr Lisa Walker to launch Proact Health, targeting major employers as facilitators of employee primary care clinics.

Dr Lisa Walker MBBS FRACGP

As Chief Medical Officer at Proact Health, Dr Walker leads clinical strategy, manages a national team of GPs, and oversees the operation of onsite clinics that deliver accessible, high-quality care to employees and organisations.
