Original Medicare psychiatric care for adults in Virginia and Florida, by video.
Physician-led medication management with Dr. Sonia Mia Diaz, MD. We bill Medicare directly. Now scheduling first visits.
Who we see, and who we can't
Adults in Virginia and Florida with Original Medicare Part B, with or without a Medigap supplement.
Medicare Advantage plans, Medicaid (including Medicare plus Medicaid), commercial insurance, patients under 18, or patients located outside Virginia and Florida at the time of the visit.
Original Medicare is the red, white, and blue card. A card with an insurance company's name on it is usually an Advantage plan.
Florida patients: we do not prescribe controlled medications, including stimulants, for patients located in Florida at this time.
What we treat
Care centers on medication management: a full evaluation, then follow-up visits with the same physician.

Pick a time below, call us, or have your doctor fax a referral to 434-404-4624.
