Canybec Sulayman, PMHNP-BC
Founder of Horizon Peak Health · Board-certified psychiatric-mental health nurse practitioner
I am dual-trained in primary care and psychiatry. After 19 years in critical care, I bring that medical lens to psychiatric evaluations and second opinions. I review the history, medication response, sleep, and lab or biomarker results when clinically indicated.
My initial diagnostic evaluation is 75 clinical minutes.

My approach
Start with the pattern
In critical care, a change in sleep, medication response, vital signs, or lab results could change the plan. I bring that habit of checking the full history into psychiatric evaluation.
We discuss what changed, what has been tried, and where the diagnosis may need another look. I review existing records and relevant biomarkers when the history points there. Testing or a medication change depends on the clinical picture; neither is automatic.
A useful diagnosis should explain the pattern. If it does not, I keep asking questions.

What I can help evaluate
Psychiatric evaluation
I review the timeline, current symptoms, treatment history, and medical context to understand the pattern before making a plan.
How evaluations work →Medication management
We look at what has helped, what has not, and what side effects or interactions may be changing the picture.
Medication care →ADHD assessment
Focus problems can overlap with sleep, mood, anxiety, and other concerns. An evaluation looks at the history rather than assuming the diagnosis.
ADHD evaluation →I also evaluate ketamine candidacy for eligible Arizona patients at the Gilbert office. Evaluation, treatment choice, and follow-up depend on the clinical review; this is not a California service.
A second opinion is appropriate when a previous diagnosis or treatment plan has not explained the full pattern. Bring prior records if you have them; I review what is relevant to the question.
Training and credentials
Psychiatry, primary-care training, and ICU experience
I hold PMHNP-BC board certification and completed adult-gerontology primary care training. I also hold an MBA, CCRN, and CSC, and I am DEA-registered for prescribing.
My ICU background includes cardiac surgery, trauma, burn, and medical care, with work at NewYork-Presbyterian, Cedars-Sinai, and USC-affiliated settings. My UCLA Anderson MBA focused on healthcare operations and entrepreneurship.
