The capital and most populous city of the U.S. state of Indiana, Indianapolis, also known as Indy, is the county seat of Marion County. In 2020, Indianapolis and Marion County had a combined population of 977,203, according to the US Census Bureau. In Marion County, the “balance” population, which does not include municipalities with limited autonomy, was 887,642.  After Chicago, Illinois, and Columbus, Ohio, it is the third-most populous city in the Midwest. It is also the fourth-most populous state capital, behind Phoenix, Arizona, Austin, Texas, and Columbus. With 2,111,040 inhabitants, the Indianapolis metropolitan area ranks as the 33rd most populous MSA in the nation. With a population of 2,431,361, its combined statistical area is 28th in the nation. Indianapolis is the 18th largest city in terms of land area in the United States with a total area of 368 square miles (950 km2).

Established in 1821

The planned city of Indianapolis was established in 1821 to serve as the new location of the state of Indiana’s government. Alexander Ralston and Elias Pym Fordham laid out the city on a grid of one square mile (2.6 km2) near the White River. The city’s status as a manufacturing and transportation hub was later cemented by the opening of the National and Michigan roads and the arrival of rail. The terms “Crossroads of America” and “Railroad City” are two nicknames for the city that refer to its earlier connections to transportation. An elected 25-member city-county council led by the mayor has been in charge of local government administration since the city-county merger, or Unigov, in 1970.

Based primarily on the sectors of trade, transportation, and utilities; professional and business services; education and health services; government; leisure and hospitality; and manufacturing, Indianapolis serves as the economic hub of the 29th largest economic region in the United States.

The amateur sports and auto racing niche markets in the city are noteworthy. Three Fortune 500 companies, the Colts and Pacers of the NBA, five college campuses, and a number of museums, including the biggest children’s museum in the world, are all located in the city. However, the Indianapolis 500, the largest single-day sporting event in the world, is perhaps what makes the city most well-known. Indianapolis is home to the nation’s largest concentration of monuments honoring veterans and war dead outside of Washington, D.C., which can be found in the city’s historic neighborhoods and sites.


More than 20 hospitals provide healthcare in Indianapolis, the majority of which are part of the private, non-profit healthcare networks Ascension St. Vincent Health, Community Health Network, and Indiana University Health. Many of them are teaching hospitals connected to Marian University’s College of Osteopathic Medicine or the Indiana University School of Medicine.

The Marion County Public Health Department, Indianapolis Emergency Medical Services, and Eskenazi Health are just a few of the public health programs and facilities that are managed by the municipal corporation known as the Health and Hospital Corporation of Marion County.

Twelve primary care facilities are run by Eskenazi Health throughout the city, including the main Sidney & Lois Eskenazi Hospital. The Richard L. Roudebush VA Medical Center, which was founded in 1932, provides care for nearly 70,000 veterans each year. In 2019, the 159-bed NeuroDiagnostic Institute, a mental health facility governed by the Indiana Family and Social Services Administration, opened.

The Indiana University School of Medicine, the largest medical school in the United States by enrollment, is affiliated with Indiana University Health’s Methodist Hospital, University Hospital, and Riley Hospital for Children.

According to U.S. News and World Report, Riley Hospital for Children is among the top pediatric medical facilities in the country in all ten specialties. The 430-bed hospital is the only pediatric Level I Trauma Center in Indiana. A new $1.6 billion academic medical center that is scheduled to open in 2026 will consolidate and replace Methodist and University hospitals, according to plans released by IU Health in 2020.

Ascension St. Vincent Hospital Indianapolis, Community Hospital East, Community Hospital North, and Franciscan Health Indianapolis are some of the city’s other significant private, nonprofit hospitals.

Our locations

In Indianapolis, Oasis TMS has two locations. Located at 9002 N. Meridian St., Suite 208, Indianapolis, IN 46260, Oasis TMS of Indianapolis.

Greenwood’s Oasis TMS is situated at 107 North State Road 135 in Suite 104. Callers can reach both at (888) 417-5973.

Our goal at Oasis TMS is to provide a setting that supports providing effective relief from depression and other mood disorders.

Transcranial magnetic stimulation (TMS) therapy uses magnetic fields to stimulate the brain’s underactive nerve cells, whereas antidepressants change your brain’s chemistry. At Oasis TMS, we deliver magnetic energy pulses to the prefrontal cortex of the brain using a state-of-the-art, FDA-approved device. Transcranial magnetic stimulation can therefore painlessly reactivate areas of the brain involved in mood regulation while enhancing central nervous system communication.

In individuals who had previously struggled with a type of treatment-resistant depression, TMS trials have demonstrated that it can have long-lasting, beneficial effects on brain function.
