A general practitioner with emergency-room experience

Her specialty is general practice. Her years in emergency rooms give 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.

What she treats by video, and what she doesn't

She treats common health problems in adults and in children from 6 months old, refills of non-controlled medications, and follow-up of stable chronic conditions. See our services and the conditions we treat.

• She is not a pediatrician. For children she treats common problems and will tell you when an in-person visit or a pediatric specialist is needed.
• She does not prescribe controlled substances.
• She does not handle emergencies or do exams that need hands-on, in-person examination. See what we don't do by telehealth.

Clinical responsibility

Every clinical decision in your visit, such as the diagnosis, whether to prescribe a medication, 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.

Her role at The Health Initiative

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, and more about the service in about us.
