Practice Manager
Trainee Behaviour Support Practitioner
Courtney Kruger is the Practice Manager and a Trainee Behaviour Support Practitioner here at Concepts Psychology. She started as our receptionist and is always at hand to assist where she can. Whether that be with scheduling, office administration or communicating with representatives from the numerous organisations and schools we work with across the greater Sydney area.

Courtney joined the team here at Concepts Psychology in 2021 after returning to Australia from a 5-year stint in Glasgow, Scotland. It was in the UK where she juggled being a mum, working at home as a receptionist during the day and then as a carer for the elderly at night. This fast paced experience taught her crucial time management skills which have enabled her to be a great fit for Office Manager.

Her responsibilities also include invoicing, email management, account keeping, diary management and relationship building. Passionate about equality, social justice and supporting those in need, she wanted to be part of a team which supports others to reach their full potential and live their best life. She enjoys meeting members of the local community in her role and working within a team that strive to empower others.

Outside of work she loves spending her spare time with family and friends either by brunching, shopping, or exploring the great outdoors.
