Questions we hear about Functional Psychiatry & Lab Testing
Telehealth results?
If you are in Florida.
Crisis?
988/ER, not a draw center.
Is GeneSight required?
No.
Who interprets?
Dr. Dorothy Chatelier, DNP, FNP-BC, PMHNP-BC.
Vitamin D religion?
We treat deficiency, not a fandom.
Do you treat based on Instagram optimal ranges?
No. We use clinical context.
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.

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.
