GeneSight is probabilistic. It is not a personality test and not required on visit one.
What Functional Psychiatry & Lab Testing actually includes
B12 psychiatric testing when risk factors exist.
GeneSight testing in Hollywood is optional and post-failure, not a rite of intake.

Clinical FAQ
Vitamin D religion?
We treat deficiency, not a fandom.
Crisis?
988/ER, not a draw center.
Do you treat based on Instagram optimal ranges?
No. We use clinical context.
Do labs replace a psychiatric diagnosis?
No.
Can labs be wrong?
Yes. We repeat when needed.
Is GeneSight required?
No.
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.

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.
