If you’re looking for reliable healthcare in the Tri-Cities area of Washington State, Trios Health is likely the name you’ll hear most. It’s a well-established regional health system serving Kennewick, Richland, Pasco, and surrounding communities. Whether you need emergency care, cancer treatment, or a routine checkup, this guide covers everything you need to know.
What Is Trios Health?
Trios Health is a multi-specialty healthcare system rooted in Eastern Washington. It serves thousands of patients across the Tri-Cities region every year, offering everything from primary care to complex surgical procedures. The system operates hospitals, clinics, and specialty centers — all focused on keeping the local community healthy.
What makes Trios Health stand out isn’t just its size. It’s the way the organization has evolved over decades to meet the real, changing needs of its patients. From urgent care walk-ins to long-term chronic disease management, Trios Health covers a broad spectrum of care under one regional umbrella.
From Kennewick General Hospital to Trios Health
The story of Trios Health starts with Kennewick General Hospital, which served the Tri-Cities community for many years before the organization rebranded and expanded its mission. The name change wasn’t just cosmetic — it reflected a shift toward a more integrated, system-wide approach to healthcare delivery across Eastern Washington.
Mission, Values & Community Roots
At its core, Trios Health is built around patient-centered, compassionate care. The organization is deeply embedded in the Tri-Cities community, prioritizing access, quality, and dignity for every patient who walks through its doors. Its values emphasize treating people — not just conditions.
Trios Southridge Hospital — The Heart of the System
Trios Southridge Hospital is the flagship facility within the Trios Health network. It serves as the primary hub for inpatient and outpatient hospital services across the region, handling everything from planned surgeries to emergency admissions. If Trios Health is the system, Southridge is its engine.
The hospital is modern, well-equipped, and staffed by experienced clinical teams. It handles a high volume of Eastern Washington hospital services daily, making it one of the most active medical facilities in the region. Patients from Kennewick, Pasco, Richland, and beyond rely on it for serious and complex care.
Location & Facility Overview
Trios Southridge Hospital is located in Kennewick, Washington, and sits at the center of the Tri-Cities metro area. The facility includes multiple inpatient units, surgical suites, diagnostic imaging, and a dedicated emergency department. Its location makes it easily accessible for most Tri-Cities residents.
Level III Trauma Center & Emergency Services
One of Southridge’s most critical designations is its Level III Trauma Center in Washington State. This means the hospital is equipped to handle serious trauma cases — stabilizing patients and, when necessary, coordinating transfers to higher-level trauma centers. The emergency department operates 24/7 and handles both walk-in and ambulance arrivals around the clock.
Medical Services & Specialties Offered
Trios Health operates as a true multi-specialty healthcare system, offering a wide range of clinical services under one regional network. Whether you’re dealing with a heart condition, a cancer diagnosis, a sports injury, or a pregnancy, there’s a care team here built for that. The depth of specialty services available is one of the strongest reasons patients stay within the Trios ecosystem.
Cancer, cardiology, and orthopedics are among the most utilized service lines. However, the system also covers women’s health, pediatrics, kidney disease, digestive health, and behavioral medicine — making it a genuinely comprehensive option for Tri-Cities families.
Cardiology & Heart Health
The cardiology program at Trios Health covers diagnostics, interventional procedures, and ongoing heart disease management. Patients with conditions like arrhythmia, coronary artery disease, or heart failure have access to cardiologists and advanced imaging technology without leaving the region.
Oncology & Cancer Care
Cancer care at Trios Health includes medical oncology, radiation therapy, and supportive services for patients and families. The team works collaboratively, meaning your oncologist, radiologist, and surgeon coordinate directly — which leads to better outcomes and less stress for you as a patient.
Orthopedics & Joint Replacement
From ACL repairs to total hip and knee replacements, the orthopedics team at Trios handles a full range of musculoskeletal conditions. If you’re managing ongoing joint problems, combining surgical care with lifestyle changes like joint pain and inflammation relief can significantly support your recovery.
Women’s Health & Birthing Center
Trios Health provides comprehensive women’s health services, including OB-GYN care, prenatal services, and a dedicated birthing center. The birthing center is designed to make labor and delivery as comfortable and safe as possible, with experienced nursing staff and private rooms.
Additional Specialties (Nephrology, Gastroenterology, Pediatrics)
Beyond the major specialties, Trios Health also offers nephrology for kidney disease management, gastroenterology for digestive conditions, and pediatric care for younger patients. The system also provides behavioral health services for patients dealing with mental health conditions alongside physical ones — an increasingly important part of whole-person care.
Trios Medical Group — Primary & Specialty Care
Trios Medical Group is the outpatient arm of the Trios Health system. It’s where most patients start their healthcare journey — with a primary care provider who can manage routine health, preventive screenings, and referrals to specialists when needed. Think of it as your front door into the broader Trios network.
The group includes both primary care physicians and specialist providers, all operating within the same integrated system. That means your records, referrals, and care plans move seamlessly between your family doctor and any specialist you see — no repeated paperwork, no information gaps.
Who Are Trios Medical Group Providers?
Trios Medical Group providers include family medicine doctors, internists, nurse practitioners, and physician assistants. Many of them take a strong preventive care approach, focusing on catching problems early before they become serious. These are primary care providers based in Kennewick and across the wider Tri-Cities area.
Care Centers Across the Tri-Cities
Trios Medical Group runs multiple care centers spread across Kennewick, Pasco, Richland, and nearby communities. This distributed model means you don’t have to drive across town to see your doctor. Most locations offer same-day appointments and extended hours for added convenience.
Trios Health & UW Medicine Partnership
One of the most significant developments for Trios Health in recent years is its formal relationship with UW Medicine as a Community Health Partner. This partnership gives Trios patients access to UW Medicine’s clinical expertise, research programs, and specialist networks — without needing to travel to Seattle.
For patients with complex or rare conditions, this connection is genuinely valuable. It also means Trios providers can consult directly with UW Medicine specialists, which elevates the standard of care available locally. Combined with expanded mental health provider networks, this partnership reflects a broader push toward whole-system, coordinated healthcare delivery in Eastern Washington.
Insurance, Billing & Patient Access
Navigating healthcare costs can feel overwhelming. Trios Health tries to simplify that experience by offering clear billing support and a wide range of accepted insurance plans. The financial services team can help you understand your coverage before treatment begins — which prevents unwanted surprises later.
If you’re unsure whether Trios is in-network for your plan, the billing department can verify coverage quickly. For patients without insurance, financial assistance programs and payment plans are also available.
Accepted Insurance Plans
Trios Health accepts most major commercial insurance plans, including plans through Washington State’s exchange. Before your appointment, it’s worth exploring your routine health check options so you know exactly what services your plan covers and what to expect at your visit.
Medicare, Medicaid & Private Pay Options
Trios Health accepts Medicare and Medicaid, making it accessible to seniors, low-income patients, and families on state assistance. Private pay options are also available with transparent pricing and financial counseling for those who qualify for assistance programs.
