Chandler, Arizona
ADHD Assessment & Treatment in Chandler
Comprehensive ADHD evaluation that investigates medical causes of focus issues before diagnosis
Our Approach in Chandler
Why Focus Problems Need Medical Investigation
Many Chandler residents struggle with focus, concentration, and productivity — and assume it must be ADHD. A meaningful share of focus problems have medical contributors that a symptom checklist alone will miss.
Before diagnosing ADHD, we investigate whether thyroid dysfunction, iron deficiency, sleep disorders, or other medical factors are causing your symptoms. When these conditions are treated, many patients experience significant improvement—sometimes without ADHD medication.
We bring diagnostic rigor from critical care medicine to psychiatric care. Your evaluation includes comprehensive lab work and medical assessment—not just a symptom checklist.

Common Questions
ADHD Evaluation FAQs for Chandler Patients
What makes ADHD evaluation at Horizon Peak Health different from other Chandler providers?
Unlike standard ADHD assessments that rely primarily on symptom checklists, our approach includes comprehensive lab work to identify medical conditions that mimic ADHD—such as thyroid dysfunction, iron deficiency, vitamin deficiencies, and sleep disorders. Our diagnostic approach brings medical rigor to psychiatric care, ensuring you get the right diagnosis and treatment.
How long does an ADHD evaluation take in Chandler?
The team confirms the visit length when scheduling. This thorough assessment includes reviewing your medical history, discussing your symptoms in detail, and considering targeted tests when indicated. We don't rush through appointments—complex cases require time to investigate properly.
Do you accept insurance for ADHD treatment in Chandler?
Whether we are in network depends on your plan, treating clinician, state, and visit type. A benefits check is not a payment guarantee. We recommend calling our office at (480) 535-6455 or your insurance provider to verify your specific coverage before your appointment.
Can thyroid problems cause ADHD-like symptoms?
Yes. Even mild thyroid dysfunction can cause cognitive slowing, difficulty concentrating, fatigue, and brain fog — symptoms that can look like ADHD. This is why thyroid testing is part of a comprehensive evaluation when clinically indicated.
How soon can I get an ADHD evaluation appointment in Chandler?
Appointment availability varies by visit type, insurance status, and whether telehealth or in-person care is the right fit. Call (480) 535-6455 or use online scheduling to request an evaluation.
Do you offer telehealth ADHD appointments for Chandler residents?
Yes. Chandler-area patients can use Arizona telehealth when clinically appropriate. In-person Arizona care is based at the Gilbert office.
