In-office versus Florida telehealth

Neighborhoods and ZIPs: 33064
Lighthouse Point sits in Broward County. County-level resources (crisis lines, hospital ERs, IOP programs) are discussed during Functional Psychiatry & Lab Testing when a higher level of care is safer than outpatient titration.
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.
Parking at 7603 Davie Road Extension is on site. Lighthouse Point patients who drive 32 minutes should plan for weekday 9:00–17:00 hours; Saturday is by appointment only.
Vitamin D treated as a personality.
Questions we hear about Functional Psychiatry & Lab Testing
Hormones?
Timed, not pellet bait.
Crisis?
988/ER, not a draw center.
Genetic privacy?
We treat it as sensitive data.
How soon results?
Depends on the lab. We schedule a results visit.
Vitamin D religion?
We treat deficiency, not a fandom.
Office for interpretation?
32 min from Lighthouse Point if in-person.
Do you offer pharmacogenetic testing?
Yes. We offer pharmacogenetic (GeneSight) testing to determine which psychiatric medications are most likely to be effective for your specific genetic makeup, reducing trial-and-error in medication selection.
What makes your evaluations comprehensive?
Our initial evaluations last 60-90 minutes and include clinical assessment, review of functional lab options, hormone screening discussion, and a personalized treatment plan — not a 15-minute med check.
What we rule in — and rule out
Fatigue, cold intolerance, hair loss, or weight change suggesting thyroid/iron.
Not indicated: weekly wellness draws.
Failed antidepressant trials considering pharmacogenetics.
Patient request after counseling on limits.
Protocol elements we do not skip
Cost consent.
Hypothesis in the note before the order.
Refer critically abnormal (e.g., severe anemia, thyrotoxicosis).
Do not start TRT off a single afternoon T.

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.
