About Us





a utopian period of justice, peace, and prosperity.

Psychology is the study of the human mind and behaviour. So, psychology is about people. Psychology is about you. All people matter, including you. And, yes, I mean you reading this!


Millennium psychology was created because of people and being passionate about helping people. I believe change is possible, no matter your background, experiences, circumstances, past or present. 


People seek psychological help at different times in their lives and often in response to specific events and situations, or due to experiencing stress and difficulties within their current circumstances; family, children, relationships, work, grief, loss, separation, legal issues or the pressures of daily living. 


At Millennium Psychology, my focus is on meeting people where they are at now, whatever the situation, difficulty or condition.


Honesty, respect and empathy are key principles and practices at Millennium Psychology. I will listen, support, counsel, shape, challenge and modify thinking and behaviour with clients to help them grow and change. People of all backgrounds and ages are welcome at Millennium Psychology.
