Vijay Singh, D.O.

Dr. Vijay Singh is a psychiatrist at Salience Health’s Allen location who brings a thoughtful, evidence-based approach to helping patients navigate complex mental health concerns. His clinical interests include depression, anxiety, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and Transcranial Magnetic Stimulation (TMS). 

Dr. Singh believes effective psychiatric care begins with understanding the whole person—not simply treating a diagnosis or individual symptoms. He takes time to understand the full scope of what each patient is experiencing and works collaboratively with them to develop an individualized treatment plan based on their needs, goals, and the latest clinical evidence. 

His approach incorporates a range of treatment options, including medication management, therapy, and TMS when appropriate. This breadth of expertise aligns closely with Salience Health’s integrated approach to mental healthcare and allows Dr. Singh to help patients consider different paths forward when symptoms are persistent, complex, or have not adequately responded to previous treatment. 

Above all, Dr. Singh wants patients to know they do not have to navigate their mental health journey alone. He strives to create an environment where patients feel heard, understood, and actively involved in decisions about their care. By combining compassionate care with current clinical guidelines and advanced treatment options, his goal is to help patients make meaningful progress toward improved mental well-being, recovery, and a more fulfilling life. 

Dr. Singh completed his psychiatry residency at the Kirk Kerkorian School of Medicine at UNLV, where he served as Chief Resident and received the Top Research Activity Award in 2026. He earned his Doctor of Osteopathic Medicine from Burrell College of Osteopathic Medicine and his Bachelor of Science in Health Sciences from the University of Arizona. He is also a member of the American Psychiatric Association. 

In addition to his clinical training, Dr. Singh brings a strong background in psychiatric research to his work with patients. His published research has examined schizophrenia, depression, sleep apnea, mood disorders, and socioeconomic factors affecting mental health. He served as lead student investigator on research examining demographic differences in the age of schizophrenia diagnosis, with findings published in the Annals of Clinical Psychiatry and presented at the American Psychiatric Association Annual Meeting. His research experience strengthens his commitment to looking beyond symptoms, considering the many factors that can influence mental health, and using evidence to guide treatment decisions. 

Outside of his clinical work, Dr. Singh enjoys traveling, discovering new restaurants, playing golf, and spending time outdoors. He is an avid sports fan who follows the Phoenix Suns, Arizona Wildcats, and Arizona Cardinals. As he establishes roots in the Dallas-Fort Worth area, he also looks forward to supporting mental health education and awareness within the community.
