Dr. Pongsapisut Poonsawatphong, widely known as “Doctor Ek,” is a prominent psychiatrist in Thailand who has made significant contributions to the field of mental health. With years of professional experience, he is recognized for his clinical expertise and his leadership in shaping mental health services that are both accessible and stigma-free. He currently serves as an executive of the SMIND network and is also the resident psychiatrist at the SMIND Mental Health Clinic located in Khon Kaen.

Dr. Pongsapisut’s career includes prior service at Srinagarind Hospital, a leading teaching hospital affiliated with Khon Kaen University, where he was actively involved in psychiatric care, education, and community outreach. His approach emphasizes not only treatment but also mental health promotion and preventive care. This philosophy is evident in the services provided at SMIND, which operates under the concept “You don’t have to be sick to come,” encouraging people to seek mental wellness proactively.

In addition to his medical career, Dr. Pongsapisut is also known for his advocacy on social issues. In October 2020, he was among the group of medical professionals who signed a public statement calling for an end to violence against peaceful protesters in Thailand. This action demonstrated his dedication to human rights, ethical responsibility, and social justice—principles that deeply influence his approach to psychiatry.
