A thorough, nuanced evaluation that goes far beyond a checklist. The process includes a comprehensive clinical interview, standardized diagnostic tools, QbTest (an FDA-cleared computer-based continuous performance task for ADHD assessment), collateral information from informants, and assessment of comorbidities. Dr. Choy brings both clinical expertise and lived experience to the diagnostic process — understanding how ADHD and ASD present in high-achieving adults, how masking obscures the picture, and how late diagnosis changes everything. For patients who have spent years feeling misunderstood, this evaluation marks the beginning of a new chapter.

Medication does more than manage symptoms—it actively shapes brain function and development. Dr. Choy employs a precision approach informed by pharmacogenetic testing, ensuring the optimal regimen and dose are tailored specifically to your biology. By integrating evidence-informed supplementation with rigorous monitoring of long-term efficacy, he moves beyond stabilization—ultimately pursuing neuroenhancement and neuroprotection.

ADHD and ASD rarely exist in isolation. Anxiety, depression, OCD, PMDD, and trauma commonly co-occur, alongside emotional dysregulation, Rejection Sensitive Dysphoria (RSD), sleep disorders, and challenges with weight management. GI dysfunction, autonomic disorders, neuroinflammatory conditions, immune dysregulation, and Chronic Fatigue Syndrome (ME/CFS) also frequently overlap. These conditions do not simply coexist — they amplify one another, compounding the difficulty of both treatment and daily life. Dr. Choy specializes in these intricate, overlapping presentations, developing a single, unified treatment strategy built around the full complexity of your neurobiology. For patients who have spent years being dismissed, misdiagnosed, or partially treated, this is the comprehensive care you have been seeking.

Executive function is the brain's CEO — managing attention, planning, impulse control, and emotional regulation. For neurodivergent individuals, these systems work differently. Dr. Choy develops personalized strategies to build the cognitive scaffolding that allows high-performers to operate at their peak — sustainably, and without burning out.

The brain and body are one integrated system — each profoundly shaping the other. Exercise, sleep, nutrition, breathwork, mindfulness meditation, and stress regulation all directly influence neuroplasticity, cognitive functioning, and emotional resilience. Dr. Choy integrates lifestyle medicine and biowearable technology into treatment plans — tracking real-world data to optimize your nervous system and elevate your mental performance.

The brain is adaptable and capable of change at any age. Through targeted therapeutic interventions, Dr. Choy helps patients build new neural pathways — strengthening the cognitive, emotional, and behavioral capacities that ADHD and chronic stress have compromised. Change is possible. It requires precision strategy and the guidance of a clinician who understands how your brain actually works.

Using his modified Bathtub Model of Stress, Dr. Choy helps high-achieving patients understand their stress physiology, recognize their personal warning signs early, and build the recovery practices that sustain peak performance. This is precision resilience engineering — purpose-built for neurodivergent minds operating at the highest levels.

Drawing on his training in psychodynamic psychotherapy and a neuroscience-based approach to emotional health, Dr. Choy offers depth-oriented therapy that addresses the underlying patterns driving emotional dysregulation, relationship difficulties, and self-limiting beliefs. For appropriate patients, Ketamine-Assisted Psychotherapy (KAP) is integrated as an advanced neuroplasticity intervention — producing rapid, measurable shifts in mood, cognition, and behavior that accelerate and deepen the therapeutic process. This is treatment designed for lasting transformation.

True mental wellness and physical vitality are inseparable — each amplifies the other. Dr. Choy integrates cutting-edge longevity medicine with psychiatric care — including GLP-1 therapies, biological age testing to measure how your body is aging at a cellular level, and comprehensive lifestyle optimization across sleep, nutrition, movement, and metabolic health.
