Christine Mikhael - Chief Executive Officer

Christine is a high-performance leader with over 30 years of experience across all facets of real estate. She was inspired to enter the world of real estate by her father, who was in property development, which led her to open and operate her own highly successful agency for many years. Christine was Australia’s youngest female real estate principal and managing director at the time. 
Christine is a respected industry expert and a highly sought keynote speaker particularly for her insights on effective leadership, organisational success, and a people-centric approach. These qualities and understandings led her to be featured in the book The Modern CEO by Jarrod McGrath. 
Christine’s passion lies in empowering teams to deliver exceptional real estate experiences, catering to the vast network of offices and teams within the LJ Hooker Group which serve tens of thousands of consumers each year. 
As the CEO of the LJ Hooker Group, Christine is committed to implementing the LJH100 business strategy, which aims to celebrate the company's 100 years of innovation in 2028 while continuing to lead the industry into the next century.
