Midwestern University (MWU) is an American non-profit graduate and professional school specializing in health sciences education. Founded in 1900 as the American College of Osteopathic Medicine and Surgery, it is the fourth-oldest medical school currently active in the state of Illinois. In 1995, it increased its presence by opening another campus in Glendale, Arizona, becoming the second medical school to teach students in the state of Arizona. It has since expanded beyond solely providing medical education and now operates ten colleges, offering degrees in dentistry, pharmacy, optometry, podiatric medicine, and other health professions.
The university is accredited by The Higher Learning Commission, a Commission of the North Central Association of Colleges and Schools. The medical schools are also accredited by the American Osteopathic Association's Commission on Osteopathic College Accreditation.
