When a medical emergency happens in Pasadena, Altadena, Sierra Madre, or anywhere across the San Gabriel Valley, the question of which hospital the ambulance heads to has a simple answer: Huntington Health. The Emergency Department at Huntington Health is the only emergency room in Pasadena and the only Level II Trauma Center in the entire San Gabriel Valley – making it the regional anchor for serious medical events from heart attacks and strokes to motor vehicle accidents and pediatric emergencies.

Huntington Health is a 544-bed not-for-profit community hospital at 100 West California Boulevard in Pasadena, founded in 1892 and operating in the same heart of Pasadena for more than 130 years. In August 2021, Huntington became an affiliate of Cedars-Sinai Health System, strengthening its ability to provide the San Gabriel Valley with accessible, coordinated, high-quality care – including collaborations on clinical services, research, clinical trials, and education.

Is This the Only Emergency Room in Pasadena?

Yes. Huntington Health is the only hospital in Pasadena with a 24/7 Emergency Department, and the only Level II Trauma Center in the entire San Gabriel Valley region of Los Angeles County. For Pasadena residents, this means that any serious medical event – chest pain, stroke symptoms, major trauma, severe pediatric illness, or any condition requiring emergency evaluation – brings them to Huntington Health’s ED.

The Emergency Department serves a much broader region than just Pasadena itself, drawing emergency cases from across the San Gabriel Valley including Altadena, Sierra Madre, San Marino, South Pasadena, Arcadia, La Cañada Flintridge, Glendale, and surrounding communities. The hospital also receives medical helicopter transports via the on-site helipad (FAA LID CL14) for the most acute trauma cases.

The ED receives ambulance traffic from multiple regional fire departments, including:

Los Angeles Fire Department – RA 35
Los Angeles County Fire Department – Squads 11 and 19
Pasadena Fire Department – RA 31, 32, 33, 34, and 36
South Pasadena Fire Department

What Is a Level II Trauma Center?

Trauma centers in the United States are categorized by levels (I through V), with each level reflecting the scope of trauma care the center is equipped and staffed to provide. A Level II Trauma Center provides initial definitive trauma care regardless of the severity of injury, with 24-hour immediate coverage by general surgeons and prompt availability of specialists in orthopedic surgery, neurosurgery, anesthesiology, emergency medicine, radiology, and critical care.

Huntington Health’s designation as the only Level II Trauma Center in the San Gabriel Valley means it is equipped to handle the most serious trauma cases in the region – motor vehicle accidents, falls from height, penetrating injuries, and other major trauma events that require coordinated, multidisciplinary emergency intervention. For trauma cases in the area that would otherwise need to be transported to LAC+USC Medical Center (Level I) or other distant Level I centers, Huntington serves as the regional anchor.

What Services Does the Emergency Department Provide?

As a Level II Trauma Center within a 544-bed full-service hospital, the Emergency Department provides comprehensive emergency medical services:

24/7 emergency medicine evaluation and treatment
Trauma resuscitation and stabilization
Cardiac emergency care – backed by the hospital’s award-winning cardiac surgery program
Stroke care – evaluation, imaging, and acute intervention
Pediatric emergency care
Diagnostic imaging on-site – CT, X-ray, ultrasound, MRI
Laboratory services 24/7
Surgical capability if emergency surgery is required, with operating rooms and ICU within the same facility
Admissions pathway to the broader hospital for patients needing inpatient care after ED stabilization

What Is the Cedars-Sinai Affiliation?

In August 2021, Huntington Hospital became an affiliate of Cedars-Sinai Health System – one of the largest and most respected academic health systems in the United States. The affiliation isn’t a merger; Huntington remains a separately operated community hospital. But the affiliation does mean a meaningful expansion of clinical capability for San Gabriel Valley patients.

The collaboration covers clinical services (specialty referrals between the systems), research, clinical trials access for Huntington patients, and education partnerships. For Pasadena residents, the practical effect is that the local community hospital is now backed by the broader expertise and resources of one of the country’s major academic medical centers – without requiring patients to travel to West Los Angeles for advanced subspecialty care.

As part of the affiliation, the hospital adopted the name Huntington Health – reflecting the broader system identity while preserving the Huntington name that has been associated with the hospital since the 1930s.

What Awards and Recognition Does the Hospital Hold?

Huntington Health has received multiple Healthgrades recognitions in recent years, including:

America’s 100 Best Hospitals for Coronary Intervention Award
Cardiac Surgery Excellence Award
Outpatient Joint Replacement Excellence Award
Superior clinical outcomes in knee and hip replacement, back and neck surgery, and rotator cuff surgery
Superior clinical outcomes treating chronic obstructive pulmonary disease (COPD) and pneumonia

In addition to clinical outcomes, the hospital reports that 74% of patients would recommend Huntington Health to family or friends – a meaningful patient experience indicator for a hospital that handles the most complex cases in the region.

How Does the Hospital Work with Doctor2me for Home-Based Care?

Emergency Department visits are usually point-of-acute care, not the start of an ongoing care relationship. After ED stabilization, patients are either admitted to the hospital, transferred to specialty care, or discharged home with follow-up instructions. For the patients who are discharged home, the next step often involves primary care follow-up, medication management, and monitoring of the condition that brought them to the ED.

Doctor2me physicians provide home visits for patients in the post-ED window – reducing the need for additional transportation to clinic visits during recovery, especially for elderly patients or those with mobility limitations. For Huntington Health ED patients discharged home with follow-up needs, in-home physician visits can be coordinated through Doctor2me at (866) 362-1499.

What About Home Health Care After an ER Visit?

For ED patients discharged home with needs that exceed routine primary care – IV antibiotics, wound care, post-surgical monitoring, respiratory therapy, or skilled nursing follow-up – home health agencies provide professional in-home medical care during the recovery period.

911 AM PM Home Health Care, Inc. is a Medicare-certified home health agency providing skilled nursing and home health services across the Greater Los Angeles area. Services include skilled nursing care, medication administration, respiratory monitoring, post-surgical care, and post-stroke care – the kind of clinical follow-up that’s frequently needed after an emergency department visit or hospital admission.

For Huntington Health patients being discharged home from the ED or inpatient stay with skilled nursing needs, the case manager can coordinate referral to a Medicare-certified home health agency as part of the discharge plan.
