Marin General Hospital is now called MarinHealth Medical Center. The hospital is still at 250 Bon Air Road, Greenbrae, CA 94904, and the main hospital phone number is (415) 925-7000. MarinHealth officially brought the former Marin General Hospital under the MarinHealth name in 2019, so patients searching the old hospital name should now look for MarinHealth Medical Center.

It includes a 24/7 Emergency Department and Level III trauma services, surgery, maternity, NICU, intensive care, cardiology, imaging, laboratory, medical/surgical inpatient units, behavioral health and numerous specialty programs.

Is Marin General Hospital still called Marin General?

The old hospital name remains common in searches, referrals and older medical documents.

The facility formerly known as Marin General Hospital is now MarinHealth Medical Center. Marin General Hospital, its foundation, Prima Medical Foundation and Marin Healthcare District Health Centers formally came together under the MarinHealth identity on July 30, 2019.

The hospital itself was not moved to another city. It remains at 250 Bon Air Road in Greenbrae. MarinHealth also states that the hospital remains independent and is owned by the Marin Healthcare District.

Search tip: if your discharge paper, referral or older insurance record says “Marin General Hospital,” use MarinHealth Medical Center when searching current hospital information, MyChart, billing, medical records or provider details.

MarinHealth Medical Center Emergency Department

Emergency and trauma services are located in the Oak Pavilion and operate around the clock.

Emergency availability 24 hours / 7 days

Emergency and trauma staff are available around the clock.

Trauma designation Level III Trauma Center

MarinHealth describes its trauma center as a Level III-N / Level III trauma facility.

The Emergency Department is inside the newer Oak Pavilion at the 250 Bon Air Road campus. MarinHealth says the expanded ED is approximately three times the size of the previous department and includes five trauma bays and 20 private patient rooms.

Separate access and treatment areas are used for trauma, psychiatric and high-security patients. Ambulance patients use a separate entrance from walk-in patients.

What happens after you arrive?

1. Arrival Hospital staff gather initial information.
2. Triage Urgency is assessed; critically ill patients are prioritized.
3. Clinical evaluation RN, physician, PA or NP evaluates the patient.
4. Testing / treatment Labs, imaging or other care may be ordered based on need.
Emergency wait time changes continuously. MarinHealth publishes a live Emergency Department wait estimate online, but it should not be copied into a static guide because the number can change minute by minute. Patients are treated according to medical urgency, not simply arrival order.

ER doctor timing: Emergency physicians work rotating hospital schedules. MarinHealth does not publish a dependable public daily rota that lets a patient reserve a particular emergency physician. ER patients are assigned to available clinicians based on staffing and clinical need.

MarinHealth campus buildings, departments and floors

The hospital uses tree names and color-coded floor levels to make navigation easier.

MarinHealth Medical Center uses four principal pavilion names: Oak, Cedar, Redwood and Cypress. Each pavilion is associated with a tree symbol, and floor levels use different colors for wayfinding.

Oak Pavilion

  • Emergency & Trauma — Lobby
  • Imaging & Radiology Check-In — Lobby
  • Surgery & Procedures Check-In — Level 1
  • ICU — Level 1
  • Maternity — Level 3
  • NICU — Level 3
  • Medical & Surgical Care — Level 4
  • Spiritual Care — Level 4

Redwood Pavilion

  • Creekside Café — Level 1
  • Outpatient Laboratory — Level 2
  • Medical Records / Administration area — Level 2
  • Radiology Extension — Level 2
  • Surgery Extension — Level 3
  • Outpatient Infusion — Level 5

Cedar Pavilion

  • Marin County Crisis Stabilization services
  • Sausalito Room

Floor colors

  • Lobby — orange
  • Level 1 — light green
  • Level 2 — green
  • Level 3 — blue
  • Level 4 — light purple

Navigation warning

There are multiple ICUs, cardiac floors and medical/surgical areas. Confirm the pavilion and floor rather than asking only for “the ICU” or “the cardiac floor.”

Oak Pavilion access: MarinHealth’s campus directory says the public connection to the Oak Pavilion is through the hospital lobby/interior connection. Follow signs rather than attempting to enter through staff-only areas.

How to make an appointment with MarinHealth

Hospital-based care and outpatient office appointments use different scheduling routes.

Identify the specialty you need. Examples include cardiology, neurology, surgery, endocrinology, OB/GYN, primary care, orthopedics, pulmonology or gastroenterology.
Search the MarinHealth provider directory. Provider pages show specialty, education, locations and contact information.
Call 1-888-627-4642 when you need general appointment routing. This is MarinHealth’s current primary and specialty care appointment number.
Confirm the actual office address. Many MarinHealth specialists see patients in Greenbrae, Larkspur, Novato, San Rafael, Petaluma or Sonoma rather than at 250 Bon Air Road.
Verify insurance and referral requirements. Ask whether your specific plan requires prior authorization or a referral.
Confirm arrival instructions. Ask for building, suite, floor, parking area and check-in time before traveling.

Doctors at MarinHealth Medical Center

Hospital-based physicians do not always operate like outpatient doctors with fixed public Monday-through-Friday appointment schedules.

MarinHealth’s provider directory includes physicians, nurse practitioners, physician assistants and other clinicians across many specialties. The examples below are providers whose current official profiles specifically list MarinHealth Medical Center.

Provider Specialty Hospital role / location Availability pattern
Susan Sun, MD Hospitalist, Internal Medicine MarinHealth Medical Center, 250 Bon Air Road Hospitalist; cares for admitted patients rather than operating a standard public clinic schedule.
Douglas E. Cohen, MD Hospitalist, Internal Medicine MarinHealth Medical Center plus an additional outpatient practice Hospitalist work is inpatient; outpatient concierge practice is a separate location.
Azita Taghavy, MD Hospitalist MarinHealth Medical Center Assigned to hospital care; no fixed public clinic-day schedule is published for inpatient service.
Dennis Orwig, MD Radiology, Diagnostic Imaging MarinHealth Medical Center Imaging services are ordered/scheduled by exam; patients generally schedule the test rather than a radiologist consultation.
Marc E. Levsky, MD Emergency Medicine MarinHealth Medical Center Rotating Emergency Department coverage; not pre-booked as a routine appointment.
Mark S. Bason-Mitchell, MD Emergency Medicine MarinHealth Medical Center Rotating Emergency Department coverage.
Henry Schwimmer, MD Emergency Medicine MarinHealth Medical Center Rotating Emergency Department coverage.
Paul Cooperman, DO Emergency Medicine MarinHealth Medical Center Rotating Emergency Department coverage.
Doctor days, office timings and “next available” appointments change frequently. MarinHealth does not publish one reliable weekly timetable for every hospital physician. Hospitalists are assigned to admitted patients, Emergency Department physicians work rotating shifts, and many specialists practice at separate MarinHealth Medical Network offices. For outpatient availability, use the provider profile or call 888-627-4642.

Doctor fees, hospital charges and Emergency Room costs

MarinHealth does not publish one flat consultation fee or one fixed ER price that applies to every patient.

Doctor visit
The cost depends on specialty, visit complexity, whether you are a new or established patient, your insurance plan and where the physician sees you.
Emergency Room
There is no single universal ER fee. Charges vary with evaluation level, lab testing, imaging, medication, procedures, supplies and professional services.
Hospital procedure
The hospital bill can be separate from surgeon, anesthesiologist, radiologist, pathologist, ambulance and other professional bills.
Personal estimate
Call MarinHealth financial counselors at 415-925-7250 for a personalized out-of-pocket responsibility estimate.

Written hospital estimate

MarinHealth’s billing information says patients can request a written estimate of their financial responsibility for hospital services. For estimate questions, contact the Admitting Department at 415-925-7243.

The hospital specifically warns that a written estimate is not a guaranteed fixed final price. Additional physician, anesthesia, pathology, radiology, ambulance or other professional charges may be billed separately.

Anesthesia billing

MarinHealth explains that the anesthesiologist bills separately for professional services. The hospital also bills for hospital equipment, supplies, staff, medications and other resources used to provide anesthesia.

Cost-saving step: before a scheduled procedure, ask for both the hospital estimate and any expected separate professional fees. Then confirm the facility and physician network status directly with your insurer.

Use the Emergency Department after the main entrance closes.

Weekends & major holidays 7:30 a.m.–6:00 p.m.

After-hours entry is through the Emergency Department.

Visitor stay time Until 10:00 p.m.

Clinical staff may restrict visits depending on patient condition or safety.

Visitor badge requirement

All visitors must wear a hospital-issued identification badge. Visitors are asked screening questions before the badge is issued.

Clinical restrictions can override general visiting hours

Nursing or clinical staff may limit visitor numbers based on the patient’s condition, infection-control precautions, unit activity or safety. Patients may also decline visitors.

Infection prevention

  • Clean your hands when entering and leaving a patient room.
  • Follow isolation signs and staff instructions.
  • Do not visit when you are sick or have contagious symptoms.
MarinHealth states that visitor rules can change at any time. If you are visiting ICU, NICU, maternity, behavioral health, an isolation patient or arriving late in the evening, confirm the current rule before traveling.

Parking and wayfinding at MarinHealth Medical Center

Use the current campus parking map because patient, visitor and staff areas are separated.

The Medical Center is located along Bon Air Road, with internal access via Schultz Memorial Drive. MarinHealth provides a campus parking and wayfinding map for the Oak, Cedar, Redwood and Cypress pavilions.

Hospital / visitor parking

Follow current signs for patient and visitor parking rather than entering the staff-parking area shown on the campus map.

Emergency parking

Follow Emergency & Trauma signs to the Oak Pavilion / Emergency Department area. Do not use routine outpatient directions during a medical emergency.

Parking price: MarinHealth’s current public parking-and-wayfinding page does not publish a dependable current visitor parking fee. Older hospital documents should not be used to assume today’s price. Follow current campus signage or call 415-925-7000 if parking cost or accessibility is important before your visit.

MarinHealth also references valet service for certain hospital visits and maternity tours, but current valet availability and any fee should be confirmed before relying on it.

  • List of prescription medications

Pre-admission testing can include medical-history review, vital signs, laboratory testing, chest X-ray and ECG depending on the planned procedure and your medical history.

Surgery-related charges may be split between the hospital, surgeon and anesthesiologist. Ask about expected separate bills during financial planning rather than assuming one estimate includes every clinician involved.

Maternity, Labor & Delivery and NICU

MarinHealth operates Marin County’s hospital-based labor and delivery service.

MarinHealth’s maternity service is located in the Oak Pavilion, Level 3. The hospital also has a Level II NICU on the same pavilion level.
