How far is Lauderhill from your office?
Our Hollywood office is approximately 20 minutes from Lauderhill via University Drive or 441. Telehealth is available for patients who prefer virtual visits.
Evidence we actually use
The Hollywood office is the only brick-and-mortar site. Functional Psychiatry & Lab Testing for Lauderhill is service-area care from that office plus telehealth — not a separate clinic in every city.
Florida telehealth for Functional Psychiatry & Lab Testing requires the patient to be physically in Florida at the time of the visit. Crossing a state line mid-treatment can pause prescribing until licensure allows.
Visit length for new Functional Psychiatry & Lab Testing is typically 60–90 minutes. Follow-up length depends on risk, controlled substances, and how many variables changed since the last visit.
In-office versus Florida telehealth
South Florida heat, hurricane disruption, shift work, and multigenerational households show up in Lauderhill presentations. Functional Psychiatry & Lab Testing intake asks about those stressors explicitly.
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.

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.
