In the USA, healthcare chains now play an important role by offering many healthcare services to people at hospitals, clinics, various centers, and even at retail locations. They rely on a broad network to ensure that people can easily receive consistent treatment at more accessible and lower costs across several states and cities. Analysis reveals that various healthcare chains have grown fast, supported by an increase in needs for easy-access, convenient, and integrated care available in one network. Because of their large size and modern technology, big chains face competition in healthcare with confidence and success.
The healthcare chains market in the USA has experienced steady growth over the past decade, driven by an aging population, increasing demand for accessible and specialized care, technological advancements, and a focus on value-based care models.

By exploring prominent chains, you can see the progress and transformations in the American healthcare system.

As of April 29, 2025, there are 9,071 CVS HealthHubs in the United States, helpfully serving customers in all 51 states and territories and in 3,451 cities. These HealthHubs are linked with CVS Pharmacy and provide additional health services like wellness advice, support for chronic diseases, and health exams, all in a convenient retail store.
California is in the lead by having 1,069 CVS HealthHub locations, which is approximately 12% of the total. This means there will be one HealthHub for every 36,962 individuals in the target area.

The United States also consists of Puerto Rico, American Samoa, Guam, the U.S. Virgin Islands, and the Northern Mariana Islands.

Quest Diagnostics
By April 25, 2025, Quest Diagnostics operates 5,758 clinics, enabling it to serve patients in 52 states and territories and 2,451 cities. These clinics are important because they supply important diagnostic services such as lab tests, routine checkups, and ongoing health monitoring.
There are 688 Quest Diagnostics clinics in Texas, which means one clinic serves every 42,145 people in the state. In California, there are 648 clinics (11%), which means around 60,975 people for every clinic. Among all states, Florida holds the third position with 479 clinics that serve 8% of the total, giving every 44,839 residents access to one clinic.

In Puerto Rico, American Samoa, Guam, the U.S. Virgin Islands, and the Northern Mariana Islands, you won’t find any clinics.

On October 24, 2023, Ascension Health oversees 3,055 hospitals in 16 states and territories and provides care to people in 396 cities in the United States.

Ascension Health
The state of Michigan is home to 624 Ascension Health hospitals in the USA, comprising 20% of the national number, and having a hospital for every 16,005 residents. Illinois comes next with 420 hospitals (14%) that provide treatment for every 30,171 people, while Indiana has 371 hospitals (12%) per 18,146 residents. Each of these states serves as proof that the organization focuses on health care for both city and countryside residents.
States and Territories without any Ascension Health Locations
At the moment, 40 states and territories do not have any Ascension Health hospitals. The list covers several states and U.S. territories like New Jersey, South Carolina, Arizona, Maine, Rhode Island, California, New Mexico, Montana, and Delaware, along with others. Places such as the U.S. Virgin Islands, Northern Mariana Islands, Puerto Rico, American Samoa, and Guam are also included in the list. California, Ohio, and North Carolina are among the large and populous states that do not have Ascension Health hospitals. Given that Ascension Health concentrates on a few regions with just over 3,000 facilities, it is clear that it does not have hospitals across the country.
LabCorp
As of April 25, 2025, LabCorp has 2,296 locations across the United States, covering patients in 48 states and territories and 1,352 cities. As a leading company in diagnostics, LabCorp offers various medical tests to physicians and patients, including pathology, bloodwork, and other specialized exams.
LabCorp has 347 facilities in California, giving every 113,867 residents access to a clinic. Florida accommodates 256 treatment sites (11%) so that one center is available for every 83,898 citizens. In New Jersey, there are 168 locations, making up 7% of the total, and each person has access to a facility every 52,869 in the community. This trend is a result of LabCorp choosing to target dense populations and regions needing a lot of diagnostics.
States and Territories without any LabCorp Locations
LabCorp is not presently available in eight states and territories of the U.S. Puerto Rico, Hawaii, American Samoa, Guam, Maine, the U.S. Virgin Islands, Northern Mariana Islands, and North Dakota are some of these areas. Lacking LabCorp in such areas suggests that it is challenging to get proper laboratory tests done, especially for those living in isolated regions.
Aurora Health Care
As at January 28, 2025, Aurora Health Care has 1,861 locations in the U.S., but most are in three states and 85 cities. Even though the organization offers many health services from primary care to advanced medicine, they only provide them in the upper Midwest.
Wisconsin is home to almost the whole Aurora Health Care network, where 1,845 locations provide the greatest density, covering one in every 3,156 people. Illinois is next with twelve sites which amounts to almost 1% of the total and provides one site per 1,056,000 individuals. Only four hospitals are located in Michigan and these serve less than 1% of the American hospital population and one site for every 2.5 million people. This demonstrates that most of Aurora’s operations are located in Wisconsin, with only occasional expansion nearby.
States and Territories without any Aurora Health Care Locations
The large and populous states and territories of California, Texas and New York, along with most other places in the U.S., lack Aurora Health Care services.
Aurora Health Care does not have any locations in 53 of the US states and territories. It refers to states found in many different regions, as well as to U.S. territories. It includes Connecticut, Minnesota, Idaho, New Hampshire, Puerto Rico, Hawaii, Missouri, Alaska, Texas, Massachusetts, Virginia, Kentucky, South Dakota, Tennessee, Nevada, Ohio, Arkansas, Vermont, Alabama, Nebraska, Utah, Louisiana, North Carolina, Iowa, Mississippi, Florida, Colorado, West Virginia, Oklahoma, District of Columbia, Maryland, Wyoming, American Samoa, Washington, Oregon, Guam, New Jersey, South Carolina, Arizona, New York, Kansas, Maine, Georgia, Rhode Island, California, Indiana, New Mexico, Montana, Delaware, U.S. Virgin Islands, Northern Mariana Islands, Pennsylvania, and North Dakota.
It demonstrates that Aurora’s healthcare system operates mainly in a narrow region and prefers to focus on a specific location instead of looking nationwide.
Ascension Health Specialty Care
As of October 24, 2023, there are 1,608 Ascension Health Specialty Care locations located in 15 states and territories in the United States, providing services to people in 269 different cities. It underlines that Ascension Health focuses on localized areas within the United States rather than planning a widespread network. The organization provides many medical specialties and the arrangements of its services seem aimed at addressing specific groups and markets.
The majority of Ascension Health Specialty Care’s facilities, accounting for 20% of the total, are in Michigan, which equates to 327 locations for every million residents. In Indiana, there are 213 locations, accounting for 13% of the total and one place for every 31,606 people. Florida has 188 parks, placing it in third place with 12 percent of the total, and every person in this state has access to parks at a ratio of one to 114,245 people. This suggests that the highest number of Ascension Health specialty care providers is found in the Midwest, especially in Michigan and Indiana, and there are fewer in Florida.
States and Territories without any Ascension Health Specialty Care Locations
Currently, there are no Ascension Health Specialty Care locations in any of the 41 states and territories in the United States. This points out that Ascension Health mainly serves people in certain regions, while much of the country remains without its specialty care services. A lack of locations in these regions could indicate that decisions are made using considerations such as the demand for healthcare, nearby resources and regional collaboration.
There are no Ascension Health Specialty Care locations in South Carolina, Arizona, Maine, Rhode Island, California, New Mexico, Montana, Delaware, the U.S. Virgin Islands, the Northern Mariana Islands, Pennsylvania, North Dakota, Connecticut, Minnesota, Idaho, New Hampshire, Puerto Rico, Hawaii, Missouri, Alaska, Massachusetts, Virginia, South Dakota, Nevada, Ohio, Arkansas, Vermont, Nebraska, Utah, Louisiana, North Carolina, Iowa, Mississippi, Colorado, West Virginia, Wyoming, American Samoa, Washington, Oregon, Guam and New Jersey.
Aspen Dental
By June 4, 2024, Aspen Dental will run 1,083 clinics in 46 states and territories, with patients being served in 890 cities. The company’s presence in so many areas and how easy it is to access shows that it is one of the most widespread networks in the dental care industry in the United States. Compared to other states, certain regions have more Aspen Dental clinics than others.
There are 130 Aspen Dental clinics in Florida, reaching 12% of the total number and one for every 165,215 residents. In terms of clinics, Texas comes after with 66 (6%) and Ohio has 56 (5%). These statistics reveal that Aspen Dental has chosen to locate its clinics in states where many people need low-cost dental services. Its position at the top is important, as it reflects Aspen Dental’s reliance on Florida in boosting its growth and patient population.
States and Territories Without any Aspen Dental Locations
At the beginning of 2024, there are still 10 US states and territories where Aspen Dental does not have any clinics. These states are US territories: Puerto Rico, Hawaii, Alaska, District of Columbia, Wyoming, American Samoa, Guam, Delaware, U.S. Virgin Islands and Northern Mariana Islands.

MinuteClinic is a walk-in clinic you can find at CVS and Target locations that offers care for illnesses, wellness exams, and vaccinations. While many Americans have heard of MinuteClinic, it is available in just certain parts of the country, following a strategy to focus on places with limited healthcare.
Texas has 96 MinuteClinic centers, which makes up about 12% of all stores in the U.S. and provides, on average, one site for every 302,042 residents. There are 95 MinuteClinic locations in Florida, which covers just over ten percent of the nationwide total and provides a clinic for every 226,084 people. The state of Ohio is home to 58 MinuteClinic sites, which represents 7% of all MinuteClinic locations in the United States, providing one site for every 201,534 residents. As a result, states with high populations and a great need for inexpensive healthcare at convenient locations receive much of this aid.

Northwell Health Hospitals
As of September 19, 2024, Northwell Health operates 840 hospitals within three states and territories and helps patients in 154 cities in the United States. New York is where 837 of these locations are found, demonstrating how strong Northwell Health is regionally in the state’s healthcare industry. Due to its network, each person in New York has access to a location, demonstrating the importance of the system for local areas.
The majority of Northwell Health Hospitals are found in New York State which includes most of their branches. There is a Northwell Health facility for every 23,243 people since there are 837 throughout the state. Connecticut boasts only 2 locations, making up a very small part of the overall tally. This means that every 1,782,500 people in Canada live within 1 facility. New Jersey also has one Northwell Health Hospital which provides care for about 8.88 million people. This data reveals Northwell Health’s main work is in New York and it is scarcely involved in other states nearby.

Conclusion
It is clear from recent trends in healthcare that more patients are interested in telehealth, retail clinics and specialty care centers. Moreover, several healthcare chains use value-based care, focusing on making care affordable and effective while joining forces with insurers and companies to help deliver proper care. Growing in high-demand areas causes healthcare chains to encounter challenges, including new regulations, a lack of workers and the need to reduce health gaps. Overall, the healthcare chain industry is expecting to consistently grow due to innovative ideas, what people want and the way the US healthcare system is changing.
