Her specialty is general practice, and she has several years of emergency-department experience. That experience gives her practice in telling apart what can be treated at home from what needs care right away, which is exactly the call a video visit has to make. If she sees a warning sign during the visit, she will tell you to go to the ER or call 911.

She sees adults and children of all ages, from babies to grandparents. If the patient is under 21, a parent with patria potestad (parental authority) or a legal guardian stays on camera for the whole visit and shows photo ID. See online doctor visits for kids.

She evaluates, diagnoses and treats. These are some of our services and the conditions we treat:

Every clinical decision in your visit, such as the diagnosis, whether to prescribe a medication, whether to order lab tests, or whether to refer you for in-person care, is made by the doctor using her professional judgment. She is responsible for the care you receive. Pages in this section show a "Medically reviewed by" line only when she has reviewed that page; see our editorial policy.

The doctor is the Founding Executive Director of The Health Initiative, the nonprofit that runs this service and receives the payments. We say so plainly so you know who is who. Read her profile at The Health Initiative (opens in a new tab), and more about the service in about us.
