Meet Your Psychiatrist: Dr. Nigel Kennedy, MBBS, PhD
Prior to completing specialist training in Psychiatry at the Icahn School of Medicine at Mount Sinai in New York, Dr. Kennedy completed Medical and Foundation Training in the UK and specialized in the field of Neurosurgery. He was awarded his PhD in Neurogenetics in 2005 from Imperial College London, funded by the Medical Research Council of the United Kingdom. His research characterized genetic variants associated with psychiatric conditions.
Dr. Kennedy completed his Psychiatry residency on the Physician-Scientist track at Mount Sinai, where he graduated as Chief Resident for Research. Post-residency, he completed a psychoanalytic fellowship at the New York Psychoanalytic Society and Institute (NYPSI). He continues to hold an academic appointment as Assistant Professor in Psychiatry at Mount Sinai and serves as an Editor for the British Journal of Psychiatry International.
His patients are typically professionals in finance, corporate leadership, entertainment, and technology who need a psychiatrist offering priority intake within 1-2 business days and evening appointments that accommodate demanding schedules.
Services
Psychiatric Treatment
Psychiatric medication is most effective when managed by a physician who understands the brain's biological and genetic architecture. Dr. Kennedy applies his background in Neurogenetics and clinical training at Mount Sinai to select, prescribe, and monitor medications for each individual. As a physician-scientist, he integrates research experience to provide evidence-based psychopharmacology for ADHD, executive burnout, depression, anxiety, and insomnia.
Whether you are seeking treatment for the first time or require a more precise approach after past treatments have fallen short, Dr. Kennedy builds a clinical plan grounded in neuroscientific insights and the latest peer-reviewed evidence.
Psychotherapy
In the traditional mental health model, treatment is often fragmented between a prescribing physician and a separate therapist. Dr. Kennedy offers integrated care, where psychiatric treatment and psychotherapy are coordinated under one roof.
His therapeutic approach draws on high-level training including a Psychoanalytic Fellowship at NYPSI. His clinical work integrates Cognitive Behavioral Therapy (CBT) and Gestalt approaches for real-time symptom management, alongside psychodynamic and psychoanalytic therapy for uncovering the underlying patterns that drive current behaviors.
Conditions We Treat
Anxiety
Anxiety significantly impacts executive function, sleep, and professional performance, particularly in high-pressure careers such as finance or entertainment. Dr. Kennedy treats generalized anxiety, panic episodes, and performance anxiety using an integrated model of pharmacotherapy and CBT. While every individual's biological response is unique, many patients begin to notice a stabilization of their initial symptoms during the first two weeks of a targeted treatment plan.
Depression
Depression extends beyond feeling sad. It disrupts biological rhythms, impacts motivation, and clouds the cognitive clarity needed for decision-making. Dr. Kennedy employs a systematic, evidence-based approach, combining neuroscience-informed psychiatric treatment with psychotherapy to restore mood stability and professional drive.
ADHD
In high-performing professionals, adult ADHD often presents as a lifetime of "compensated" symptoms that can eventually lead to burnout. Dr. Kennedy conducts evidence-based evaluations to correctly diagnose and differentiate ADHD from look-alike conditions. Treatment plans include optimized stimulant or non-stimulant protocols paired with behavioral strategies to enhance focus and workplace productivity.
Insomnia
Whether a primary condition or secondary to anxiety or medication, disordered sleep is a barrier to recovery. Dr. Kennedy evaluates sleep patterns to provide a full-spectrum approach, including CBT for Insomnia (CBT-I), specialized psychiatric treatment, and adjustment of existing prescriptions to restore recuperative rest.
PTSD
Trauma-informed care requires a foundation of clinical trust and biological stabilization. Dr. Kennedy uses psychodynamic therapy, CBT, and targeted medication to help patients process trauma and regain their high level of function. For patients who need more intensive trauma work, he coordinates referrals to specialist therapists outside of the practice.
Executive Burnout
Chronic professional stress can take many forms including high levels of worry, feelings of inadequacy, tearfulness, social withdrawal, and a lack of joy in everyday activities. Dr. Kennedy specializes in treating professionals from the finance, legal, tech, and entertainment sectors. The practice offers priority onboarding within 1-2 business days, evening hours, and seamless telehealth across New York and California.
High-functioning careers demand an elite level of psychological fortitude. I work with professionals to rebuild the physiological and mental reserves necessary to excel in professional life without sacrificing the moments that matter at home.
