Hypothesis-driven testing, not a shotgun cart
We will decline uninterpretable 80-marker wellness panels.
Clinical scope of Functional Psychiatry & Lab Testing in Broward County
Functional psychiatry labs are hypothesis-driven tests inside a psychiatric evaluation.
Root cause psych labs still require a root-cause differential, not a shopping cart.
Indications and differentials
Treatment-resistant depression with never-checked B12/ferritin/TSH.
Perimenopausal or hypogonadal clues.
Fatigue, cold intolerance, hair loss, or weight change suggesting thyroid/iron.
Failed antidepressant trials considering pharmacogenetics.
In-office versus Florida telehealth
Commute noise on I-95 and the Turnpike changes whether an in-office Functional Psychiatry & Lab Testing visit is realistic this week. Telehealth is used when the clinical exam does not require the office.
Plantation (Broward County) has about 92,000 residents. The nearest Peace & Heart Wellness exam room is the Hollywood office, about 18 minutes from Westfield Broward and the University Drive medical corridor.

Questions we hear about Functional Psychiatry & Lab Testing
Vitamin D religion?
We treat deficiency, not a fandom.
Office for interpretation?
18 min from Plantation if in-person.
Adrenal fatigue?
Not a diagnosis we sell.
What if labs are normal?
We still treat the psychiatric diagnosis if it is there.
Do you treat based on Instagram optimal ranges?
No. We use clinical context.
Can labs be wrong?
Yes. We repeat when needed.
How long is the drive from Plantation?
Our Hollywood office is approximately 15-20 minutes from Plantation via 595 or Broward Boulevard. Telehealth is also available for follow-up appointments.
Do you take a functional approach to psychiatry?
Yes. Beyond traditional medication management, we investigate root causes including hormone levels, thyroid function, and nutritional deficiencies — an approach Plantation patients particularly value.
Monitoring and safety in Functional Psychiatry & Lab Testing

Florida telehealth psychiatry is available to established and new patients located in Florida at the time of the visit, subject to licensure and clinical appropriateness. An in-person evaluation at the Hollywood office may be recommended when a physical exam, vital signs, or a more complete diagnostic interview is needed.
