Dr. Antoinette Campbell Johnson founded Care Hub JA after ten years of practising psychiatry and seeing the specific need for holistic mental health treatment. She has had experience working in general hospitals (UHWI and KPH), mental health hospitals (Bellevue Hospital), health centres, child guidance clinics and specialised clinics such as clinics for persons living with HIV. 

She is a consultant psychiatrist who has a vested interest in helping people become the best they can be. She believes good mental health is the key to healthy decisions and practices, which inevitably lead to a healthy life. 

She particularly enjoys working with children, adolescents and young adults, helping them to navigate the rapidly changing stages of their development, which often come with mental health challenges. 

She believes a psychiatrist should not work alone but be involved with a team of professionals in order to treat the whole person. She believes mental health treatment should be collaborative, personalised, empathetic and enable the person to feel empowered to manage 

When she is not in office, she enjoys travelling, grabbing coffee and spending time with family.
