Culture and recreation

Wilmington is situated within one hour driving distance to Dayton, Cincinnati, and Columbus. In the mid 90's, the annual Banana Split Festival was started to commemorate the town's alleged creation of the famous treat in Wilmington in 1907. In addition, each year the city hosts the Clinton County Corn Festival, which pays homage to the agricultural tradition of the county. In 2007, a new festival, the Hometown Holidazzle, was started, taking place in the late fall. Aside from the annual events, Wilmington played host to a festival each year that a new Harry Potter book was released. Thousands would gather in downtown Wilmington at the Books 'N' More bookstore and surrounding businesses to celebrate each release.

Located in the downtown business district is the historic Murphy Theatre, which can be seen in the film Lost In Yonkers, part of which was filmed in the city in the early 1990s. The Murphy Theater stages productions throughout the year from various acts and ensembles as well as staging musicals and plays from neighboring school districts in the county. More recently, the Murphy is home to free screenings of classic movies, sponsored by a community group. The Murphy Theatre saw the marriage of actor John Ritter and wife Amy Yasbeck on September 18, 1999, with the marquee simply stating "Congratulations John and Amy." Nearby in downtown Wilmington is the historic General Denver Hotel, which is named in honor of General James W. Denver, founder of the city of Denver, Colorado. General James Denver is also buried in Wilmington.

Economy and business

In the early 1950s the city became home to a number of U.S. Department of Defense facilities, most notably the Clinton County Air Force Base. Following its closure in 1971, the economy of the city hovered in recession for more than a decade. After a number of small attempts to reuse the abandoned air force base, Airborne Express purchased the facility in 1979 for $850,000, a fraction of the estimated $100 million spent to construct it. During the next 24 years, Airborne invested more than $250 million to build a hub for its national delivery network, including new sort centers, a 9,000-foot (2,700 m) runway, aircraft hangars, machine shops, flight simulators, a state of art control tower, and a modern administration building to accommodate an estimated 6,000 employees and its fleet of 125 DC-8, DC-9 and Boeing 767 aircraft.

In 2003, Airborne Express reorganized and ABX Air, Inc. was created. ABX Air is a contract freight forwarding business whose primary customer is DHL, one of the world's largest international shipping firms. ABX's parent company, Air Transport Services Group, is based in Wilmington. Owned by the Deutsche Post WorldNet, a German holding company, DHL consolidated its US flight and sorting hub operations in Wilmington in 2005. Restructuring in May 2008 resulted in eight thousand layoffs, and six months later the Wilmington hub was closed, resulting in another eight thousand layoffs.

The facility closed in July 2009, and DHL moved to a much smaller sorting operation at the Cincinnati-Northern Kentucky International Airport. Wilmington's airport hosts a comparatively smaller Maintenance Repair and Overhaul venture, along with Airborne Maintenance and Engineering Services, employing several hundred employees under the auspices of the ABX Air parent company, ATSG (Air Transport Services Group).

On July 16, 2009, the Wilmington City Council voted unanimously to establish Wilmington as a "Green Enterprise Zone". The legislation will facilitate green economic development by creating financial incentives for the creation of green collar jobs. The City Council passed the measure in response to an economic grassroots movement initiated in October 2008 by two Wilmington High School graduates, Mark Rembert and Taylor Stuckert, aided by Pure Blue Energy, LLC a consulting firm out of North Carolina. Wilmington is the first city in the United States to pass such a law.

The AZEK Company has main flagship manufacturing plant located in Wilmington, which produces composite decking and railing systems under brand TimberTech & AZEK. With this Green Enterprise Zone initiatives in place, AZEK company in 2018 opened state-of-the-art Polyethylene recycling plant in Wilmington Airpark which recycles post-industrial and post-consumer polyethylene and makes it into raw material for TimberTech decking.

Wilmington is also home to CMH Regional Health System, a regional health provider. From its base of operations at Clinton Memorial Hospital, the non-profit corporation has established health clinics in almost a dozen satellite locations in Southwestern Ohio. In 2007, CMH opened the Foster J. Boyd, MD, Regional Cancer Center in Wilmington, providing cancer treatment services for patients throughout Southwest Ohio. The hospital in Wilmington has 95 staffed beds, and employed nearly 1000 people as of fiscal year 2006. The hospital also offers a six-bed Intensive Care Unit, a dedicated Emergency Room (with an average of over 30,000 visits from 2004–2006), an Obstetrics Unit (with 725 births in FY 2006), Surgical services (6,356 surgical procedures and 1,184 endoscopies FY 2006), Medical-Telemetry care, Medical-Surgical and Pediatric care, Physical Rehabilitation, Nuclear Medicine and CT services, and a Sleep Study center, amongst other various professional services at the hospital. RegionalCare Hospital Partners of Brentwood, Tennessee, purchased Clinton Memorial Hospital on November 30, 2010. The total sale price after adjustments was $82,137,477.

In addition to air freight services and medical services, the city of Wilmington also competes in the truck freight industry, serving as corporate home to R+L Carriers, a trucking and shipping company located off of the intersection between U.S. 68 and I-71 north of Wilmington.


The Wilmington City Schools system includes Roy E. Holmes Elementary, Denver Place Elementary, East End Elementary, as well as Rodger O. Borror Middle School (formerly known as Wilmington Middle School) and Wilmington High School. The school district includes 166 square miles (430 km2), and is the largest in the county. ACT scores are above both the state and national averages, and over three quarter of students go on to attend college, which is far above the state average of 40% although both are the lowest among the four high schools within the county.

In addition, two college campuses are located in the city. Southern State Community College operates its North Campus in Wilmington, with other campuses in Washington Court House, Hillsboro, and Sardinia, with primary focus on transfer credits and health sciences, such as Nursing and Medical Assisting and Respiratory Therapy, as well as a Practical Nursing.

Most notable is the campus of Wilmington College, a Quaker established college that dates from the nineteenth century, which focuses on liberal arts education with themes of global peace and understanding and majors in agriculture, education, athletic training, and small business.

The city is served by one of two branches of the Wilmington Public Library system.
