Experience with First Responders and Defence Personnel
Dr L has treated patients who have been first responders, as well as military and ex-military personnel. Having served in the Singaporean military himself, he brings an additional understanding of the demands of service life. While he has not undertaken specialised training in the psychiatric management of this cohort, his psychiatric training included the treatment of conditions common among first responders and defence personnel, such as PTSD, panic disorder, and major depressive disorder. Dr L has also published research exploring dissociative experiences, including psychotic symptoms, in trauma-exposed populations such as this group.

Please note: Dr Leon does not provide diagnosis or treatment for Autism Spectrum Disorder (ASD) or eating disorders.
