Getting to know Dr. Sonia Diaz
I'm Sonia Mia Diaz, MD, founder of Welmivia. I see adults by video for psychiatric evaluation and medication management: depression and anxiety later in life, sleep problems, bipolar disorder, ADHD, and burnout. I also review medications for people taking several at once. Visits are unhurried, and every visit is with me.
I accept Original Medicare Part B and bill Medicare directly. If you have commercial insurance, you pay me directly, and I provide a superbill you can submit to your plan for out-of-network reimbursement. Adult children looking into care for a parent are welcome to reach out.
For patients in Florida, I don't prescribe controlled medications, including stimulants. Not a crisis service. In an emergency, call 911 or 988.
What should a new client know about working with you?
Your first visit is a full psychiatric evaluation. We review your history, current symptoms, past treatment, and any labs or records you have, and you receive a written plan afterward. Follow-ups are 30 minutes and focus on how treatment is working. I don't continue controlled medications prescribed elsewhere without completing an evaluation first. For patients in Florida, I don't prescribe controlled medications.
What is your typical process for working with clients?
Every new client starts with a Precision Psychiatric Evaluation, a comprehensive session that goes well beyond a standard intake. We review your full history, current symptoms, prior treatment attempts, and relevant labs to build a complete clinical picture before making any recommendations.
From there, I develop a personalized treatment plan, the Welmivia Blueprint, that may include medication strategy, targeted supplementation, and specific neurooptimization techniques suited to your goals.
Follow-up visits are where the plan gets refined. I track how you're actually responding, not just whether symptoms have resolved, and adjust as needed.
Members have ongoing access for questions and check-ins between visits, so care doesn't stop at the appointment. Annual reviews keep the plan current as your needs change.
Throughout, my goal is precision over speed. I would rather take the time to get a treatment plan right than rush you through a fifteen-minute visit and hope for the best.

More information on payments and coverage
Welmivia is a direct-pay practice and does not accept insurance. This allows for longer visits, more clinical flexibility, and treatment decisions made without insurance restrictions on time or approach.
A $150 deposit is required for all patients to secure the initial Precision Psychiatric Evaluation. For follow-up visits, à la carte patients pay a $50 deposit to book; Core and Signature members are not required to pay a deposit for follow-ups. The remaining balance is collected before the start of your appointment on the day of your visit.
For clients who prefer ongoing care, Welmivia offers Core and Signature membership tiers, which include a set of services at a flat monthly or annual rate along with discounted rates on additional visits and labs. À la carte visits are also available for those who prefer to pay per session without a membership.
Some services, including specialty lab panels, are billed separately from visit fees regardless of membership status. Details on what is included in each plan are reviewed during your initial evaluation, and our team is happy to answer any billing questions before you book.
Superbills for insurance reimbursement upon request. Clients are welcome to check with their insurance provider regarding out-of-network mental health benefits.
