A Science-Based, Personalized Approach to Anxiety

Anxiety disorders are complex and can be driven by multiple factors—biological, psychological, and situational. That’s why Principium Psychiatry approaches anxiety with a comprehensive and personalized treatment model, integrating psychotherapy, psychopharmacology, interventional psychiatry, and precision diagnostics.
Our psychiatrists begin with a thorough diagnostic evaluation, exploring your medical history, life context, stressors, and symptom patterns. From there, we create an individualized treatment plan that can include one or several of the following evidence-based modalities:

Psychopharmacology

Our board-certified psychiatrists specialize in carefully tailored medication management for anxiety. We prescribe when appropriate, using the latest clinical data and pharmacogenetic insights to guide treatment. Depending on your needs, this might include SSRIs, SNRIs, benzodiazepine-sparing protocols, beta-blockers for performance anxiety, or augmentation with other psychotropic agents. Medication management is collaborative and closely monitored to ensure safety and efficacy.

Psychotherapy

Psychotherapy remains the cornerstone of effective anxiety treatment. Principium’s therapists offer evidence-based modalities such as Cognitive Behavioral Therapy (CBT), Exposure and Response Prevention (ERP) for obsessive-compulsive symptoms, and Acceptance and Commitment Therapy (ACT). For patients with trauma-related anxiety, we integrate trauma-informed psychodynamic therapy and Eye Movement Desensitization and Reprocessing (EMDR). Each therapy plan is tailored to help patients understand the roots of their anxiety, build resilience, and learn practical strategies to manage symptoms in daily life.

Precision Diagnostics

At Principium, we incorporate genetic and metabolic testing to guide treatment decisions. Pharmacogenetic testing can identify how your body metabolizes medications, reducing trial-and-error prescribing. We also consider thyroid, hormonal, and inflammatory markers when evaluating anxiety that may have underlying biological contributors.

Interventional Psychiatry: TMS and Ketamine

For patients whose anxiety does not fully respond to medication or therapy, Principium offers advanced interventional psychiatry treatments.

  • Transcranial Magnetic Stimulation (TMS)

    This FDA-approved, non-invasive treatment uses magnetic pulses to stimulate regions of the brain involved in mood and anxiety regulation. While best known for depression, TMS has shown significant benefit for generalized anxiety and obsessive-compulsive disorder (OCD).

  • Ketamine and Esketamine (Spravato®)

    Ketamine can be highly effective for patients whose anxiety is accompanied by depression or who experience chronic, refractory anxiety. Principium’s clinics in Manhattan, Greenwich, Santa Monica, and the Hamptons offer both IV ketamine infusions and intranasal Spravato®, administered by trained psychiatrists in a safe, comfortable setting.

Conditions We Treat

Our clinicians are experts in diagnosing and treating the full spectrum of anxiety disorders, including:

  • Generalized Anxiety Disorder (GAD)
  • Panic Disorder
  • Social Anxiety Disorder
  • Obsessive-Compulsive Disorder (OCD)
  • Post-Traumatic Stress Disorder (PTSD)
  • Specific Phobias
  • Health Anxiety and Somatic Symptom Disorder
  • Performance Anxiety
  • Adjustment Disorders with Anxiety

Because anxiety frequently overlaps with depression, insomnia, trauma, or medical conditions, we design integrated treatment plans that address the full picture of your mental health.

Why Choose Principium Psychiatry?

Leadership and Expertise

Principium Psychiatry was founded by Dr. Ziv E. Cohen, a board-certified psychiatrist and Clinical Associate Professor at Weill Cornell Medical College.

Our psychiatrists are leaders in interventional psychiatry, psychopharmacology, and forensic and academic psychiatry, bringing world-class expertise to each patient encounter.

Multidisciplinary, Collaborative Team

Anxiety rarely exists in isolation, and neither does Principium’s treatment approach. Our team includes psychiatrists, psychotherapists, nurse practitioners, and clinical psychologists who collaborate on each patient’s care plan. This team-based model ensures that medication, therapy, and lifestyle interventions are coordinated for optimal results.

Advanced Interventions for Complex Anxiety

For patients with treatment-resistant anxiety or co-occurring depression, Principium offers a full suite of interventional options rarely available in private practice settings.

Our clinicians are not satisfied with partial improvement—we aim for true remission and restored quality of life.
