Focus and cognitive performance
ADHD, anxiety, sleep debt, stimulant side effects, thyroid dysfunction, iron deficiency, depression, burnout, and medication burden can all look like poor focus.
San Francisco Diagnostic Psychiatry
Diagnostic Optimization for Founders, Engineers, and High-Performing Professionals
A medical-first evaluation for the San Francisco patient whose focus, mood, sleep, energy, medications, metabolic signals, and longevity interests are too interconnected for a quick symptom checklist.

The San Francisco Use Case
The question is not just "What diagnosis do I have?"
In the tech community, performance problems often arrive with a complicated story: extreme workload, compressed sleep, stimulant exposure, frequent travel, intense exercise, GLP-1 use, supplement stacks, prior psychiatric labels, and a strong desire to keep improving.
Diagnostic optimization is built for that complexity. It asks what is actually driving the signal before adding another medication, supplement, wearable metric, or protocol.
Horizon Peak Health is led by Canybec Sulayman, PMHNP-BC, and focuses on diagnostic psychiatry with medical investigation. The approach is practical, clinically grounded, and designed to reduce guesswork.
This page is built for patients asking:
- Is this ADHD, burnout, sleep debt, depression, anxiety, medication mismatch, or something medical?
- Why do I still feel cognitively off despite doing many of the "right" health behaviors?
- How do I pursue biohacking or longevity goals without ignoring psychiatric or medical risk?
Common Signals
Performance bottlenecks usually have more than one layer
The work is to separate the primary driver from the noise, then sequence care around what is most likely to help.
Energy and recovery
Low drive, slow recovery, afternoon crashes, and flat motivation deserve a differential that includes sleep, hormones, metabolic risk, nutrition, medications, and psychiatric state.
Mood under pressure
Irritability, rumination, emotional volatility, and decision fatigue are evaluated in the context of workload, nervous-system load, medical factors, and prior treatment response.
Clinical Process
A deeper evaluation before a bigger stack
This is a diagnostic pathway, not a shortcut. The goal is to understand the patient well enough to avoid low-yield interventions and catch problems that are easy to miss.
01
Map the signal
We start with a detailed psychiatric and medical history, prior medication response, sleep pattern, performance demands, labs, supplements, and current goals.
02
Build the differential
Symptoms are sorted into plausible psychiatric, sleep, metabolic, hormone, medication, nutrition, and medical contributors before treatment is intensified.
03
Sequence the plan
The goal is not more interventions. It is the right next move: medication adjustment, targeted testing, sleep work, medical coordination, or a higher-yield behavioral target.
04
Measure and refine
Follow-up looks at function, side effects, sleep, mood, focus, labs when relevant, and whether the original diagnostic model still fits.
What We Check
The point is to reduce clinical noise before adding more inputs
San Francisco optimization culture can create a long list of interventions. This evaluation works backward from the pattern and asks which signals are actually useful.

Good fit
- + Founders, engineers, investors, executives, and high-responsibility professionals in San Francisco
- + People with focus, sleep, mood, energy, or medication questions that have not been fully explained
- + Patients interested in longevity or biohacking who want clinical guardrails and a medical differential
- + Private-pay or cash-service patients who want deeper diagnostic work than a standard brief medication visit
What this is not
- - A one-size-fits-all performance protocol
- - A casual supplement stack or anti-aging promise
- - A replacement for emergency psychiatric care
- - Diagnosis or prescribing without a proper clinical evaluation
- - A shortcut around primary care, cardiology, sleep medicine, endocrinology, or emergency care when those are needed
- - A promise to prescribe peptides, hormones, stimulants, GLP-1s, or controlled substances on request
Biohacking With Guardrails
If you are optimizing, start by making the diagnosis cleaner
The best optimization work is not just aggressive intervention. It is knowing when a symptom reflects a psychiatric disorder, a medical contributor, a medication problem, a sleep problem, a metabolic signal, or normal adaptation to an unsustainable workload.
For patients already interested in wearables, longevity, GLP-1 medications, hormone questions, nootropics, supplements, or performance tracking, the clinical value is not chasing every signal. It is deciding which signal deserves action first.
FAQ
Diagnostic Optimization Questions
What is diagnostic optimization?
Diagnostic optimization is a deeper medical-psychiatric evaluation for people whose focus, mood, sleep, energy, medication response, metabolic risk, hormones, or performance goals overlap. The purpose is to clarify drivers before adding more treatment.
Is this the same as biohacking?
No. Biohacking can mean many things. This service uses psychiatric assessment, medical history, lab context when appropriate, medication review, and clinical reasoning to reduce guesswork and avoid one-size-fits-all protocols.
Do you see San Francisco tech professionals?
Yes. Horizon Peak Health serves San Francisco founders, engineers, executives, investors, and other professionals by California telehealth now. In-person San Francisco diagnostic optimization visits begin June 2026 on a limited monthly cadence — booking now.
Is this insurance-based care?
Some psychiatric services may use insurance, but deeper diagnostic optimization may involve private-pay components depending on scope, time, and goals. The practice can clarify fit and coverage before scheduling.
What should a founder or engineer bring to the first visit?
Bring the actual medication list, supplement bottles or photos, wearable sleep summaries if you track them, prior labs, blood pressure readings if stimulants are involved, the real weekly schedule, and a timeline of when focus, mood, sleep, or energy changed.
Do you prescribe peptides, NAD, hormones, or GLP-1s?
This page is not a promise to prescribe any specific intervention. The role of diagnostic optimization is to sort the psychiatric and medical picture, identify risk, decide what needs referral or coordination, and avoid adding interventions before the signal is clear.
Can this help if ADHD medication stopped working?
Yes, when the concern is appropriate for outpatient evaluation. The work is to determine whether the medication stopped working, the dose or timing is wrong, sleep or nutrition changed, anxiety or depression is louder, stimulant/caffeine load is too high, or the original diagnosis needs to be revisited.
