Dr. Nigel Kennedy, MBBS, PhD, is among the best psychiatrists in NYC, bringing a career defined by understanding the brain's complex architecture to his private practice in Midtown Manhattan. His clinical approach draws on extensive training across neuroscience, surgery, and psychiatry, with licensure in both New York and California.

Dr. Kennedy's career began in the laboratory, where he earned a PhD in Neurogenetics from Imperial College London in 2005. Funded by the UK Medical Research Council, his doctoral research investigated genetic variants underpinning schizophrenia, developing a foundational expertise in evidence-based medicine.

Transitioning from molecular research to the front lines of medicine, Dr. Kennedy earned his medical degree, a joint honors Bachelor of Medicine and Bachelor of Surgery (MBBS) from St George's, University of London. He subsequently completed Foundation Training and specialized in Neurosurgery within the UK's National Health Service (NHS), diagnosing and treating high-acuity conditions of the brain and spine.

This trajectory, from genetic mapping to surgical intervention, eventually led him to New York to focus on the psychological and biological intersections of mental health. He completed his psychiatry residency on the Physician-Scientist track at the Icahn School of Medicine at Mount Sinai, where he served as Chief Resident for Research. During his tenure at Mount Sinai, he led investigations into advanced brain stimulation techniques while refining his role as a clinician and educator. Post-residency, Dr. Kennedy completed a psychoanalytic fellowship at the New York Psychoanalytic Society and Institute (NYPSI).

"My career has been a systematic path to understand the brain across three distinct dimensions: as a scientist decoding DNA, as a surgeon treating life-threatening pathology, and now as a psychiatrist optimizing mental health and executive resilience."

Today, Dr. Kennedy leads Kennedy Psychiatric in Midtown Manhattan. Here, he synthesizes his scientific rigor and surgical precision to provide a superior standard of care for professionals navigating ADHD, executive burnout, insomnia, depression, anxiety, and PTSD.
