About Us

Because care goes beyond treatment — it starts with understanding

At Promise Healthcare, we believe care should be personal, stigma-free, and supportive. From mental wellness to preventive care, our team is dedicated to creating a safe space where you feel heard, understood, and empowered to take control of your health.

Founded to bridge the gap between medical expertise and compassionate support, Promise Healthcare has grown into a trusted provider of holistic, confidential care. We’re passionate about breaking down barriers to healthcare so you can take your first step toward well-being with confidence.

“To make stigma-free, personalised healthcare accessible to everyone who needs it.”

Dr Munidasa Winslow
Founder of Promises Healthcare

Personalized mental health and addiction care for every stage of life

At Promises Healthcare we understand that seeking support for mental well‑being takes courage. Founded in 2011 by psychiatrist and addictions specialist Dr Munidasa Winslow, our practice has grown into Singapore’s most comprehensive private mental health ecosystem.

From outpatient psychiatry and psychotherapy to residential rehabilitation and professional training, we deliver care that is both evidence‑based and deeply human. Our clinicians work together across specialties, integrating the latest research with compassion. We are proud to be the only private clinic in Singapore to offer Transcranial Magnetic Stimulation (TMS) as an option for medication‑resistant depression.
