Diagnostic psychiatry consultation at Horizon Peak Health

Our Services

Diagnostic Psychiatry Services

Medication review, diagnostic clarity, and ADHD evaluation for patients in California and Arizona when symptoms, labs, sleep, hormones, and medication history need to be read together.

Medication review

Medication is not working, side effects are getting messy, or the regimen has grown over time.

Diagnostic clarity

Symptoms do not match the label, labs were never reviewed, or the body story is missing.

ADHD evaluation

Focus, burnout, sleep, anxiety, and executive function are tangled together.

Our Approach

Diagnostic Psychiatry

Systematic root-cause investigation identifies the underlying medical factors—thyroid function, nutritional status, sleep quality, hormones—that limit mental clarity, energy, and mood.

Whether you're struggling with treatment-resistant symptoms or seeking to optimize from 'functional' to 'exceptional,' comprehensive medical-psychiatric assessment changes outcomes.

The goal is a plan that explains the pattern before treatment gets more complicated.

Clinical Areas

Core Services & Clinical Areas

Comprehensive diagnostic psychiatry addressing the full spectrum of mental health needs

1

Comprehensive Medical-Psychiatric Assessment

Systematic 16-system investigation and 75-90 minute initial evaluation. We look at the whole picture.

2

Psychiatric Symptoms Not Improving

When standard treatment isn't working, we look deeper. We investigate underlying medical causes that may be mimicking or worsening psychiatric symptoms.

3

Perimenopause & Women's Hormonal Health

Investigating hormonal changes that affect mood, anxiety, and cognition. We don't just treat the symptom; we look at the hormonal context.

4

Men's Hormonal Health & Low Testosterone

Evaluation of testosterone and related medical factors when mood, energy, libido, or focus changes may have a hormonal component.

5

PTSD & Trauma-Related Symptoms

Trauma affects the body. We explore medical factors that may be hindering trauma recovery, such as inflammation or sleep disorders.

6

Insomnia & Sleep Disorders

Root-cause investigation of sleep problems. Sleep is foundational to mental health. We check for apnea, circadian issues, and more.

7

Comprehensive Medication Management

Psychiatric prescribing with medical oversight, side-effect review, interaction checks, and a clear reason for each medication change.

8

Medical Optimization for Plateaued Patients

For patients who are functioning but still unclear about sleep, labs, medication response, hormones, or metabolic factors.

9

Professional Optimization

Diagnostic work for executives, professionals, and high-responsibility patients whose focus, sleep, mood, and medical signals are tangled together.

10

Executive Burnout & Fatigue

Medical-psychiatric evaluation of performance decline, including sleep, medication effects, mood, workload, and physiologic contributors.

11

Second Opinions & Diagnostic Clarity

Fresh perspectives on unclear diagnoses. If you've been given multiple labels without a clear path forward, we can help.

12

Pre-Surgical Psychiatric Clearance

Expert evaluations for surgical candidates (e.g., bariatric, transplant, spinal cord stimulator).
