About Dr. Lewis

Dr. Lewis is a board-certified family physician. She graduated magna cum laude from Harvard University with a concentration in medical ethics and attended Georgetown University School of Medicine. She completed a primary care residency at UCSF/Sutter Medical Center in Santa Rosa and a fellowship in women's health and family planning at the University of Southern California.

Dr. Lewis has worked as a concierge physician in the Bay Area since 2016. North Bay Private Medicine is a concierge membership practice where she limits her patient volume to 150 patients at any one time. Membership includes an extensive annual evaluation and health analysis lasting 1.5 to 2 hours, plus same-day and next-day appointments averaging 30 to 60 minutes.

Members have direct after-hours access to Dr. Lewis by cell phone for urgent needs. She will make house calls in San Francisco and Marin when her schedule allows, and depending on the membership type there may be additional fees for care outside the office. She offers care to adults and teenage patients.

Her philosophy is to form a personal partnership with her patients.

Membership and fees

North Bay Private Medicine operates on a subscription and/or fee-for-service model, is out of network, and offers complimentary claims submissions to the patient's insurance company.

On the Traditional Plan, patients pay a lower flat annual membership fee plus fee-for-service charges for in-person or telehealth visits, and the practice submits those charges to the insurance company on the patient's behalf.

Dr. Lewis is opted out of Medicare and Medi-Cal, so patients cannot seek reimbursement from those plans.
