About Dr. Long

Dr. Marta Long founded and owns Marta Long MD, a micropractice in Irvine that brings direct primary care in internal medicine to patients at home. The practice sees patients throughout Orange County. She earned her medical degree at Yale University School of Medicine.

Members have a direct phone number for her, and she is available by phone around the clock, every day. The practice offers same-day or next-day appointments and prefers one hour for each visit so patients are heard and never rushed. The practice accepts a limited number of members so it can care for them privately and attentively.

The practice makes house calls, bringing nearly everything a clinic has to patients who are very busy, ill or frail and cannot leave home. Every aspect of care comes from a physician rather than a physician assistant or nurse practitioner. The practice addresses root causes.

She offers acupuncture when appropriate and reviews patients' symptoms to see whether they are related to a medication.
