Since Cleveland Clinic’s founding in 1921, our innovations have transformed medicine. We imagine the best care possible, invent it through research, then share it with the world. Key breakthroughs:

  • Discovery of serotonin, a neurotransmitter that affects body and mood (1948).
  • Pioneering “stopped heart” surgery (1956) and coronary artery bypass surgery (1967).
  • Development of coronary angiography to reveal artery blockages (1958).
  • Establishment of cadaver donor use in kidney transplants (1963).
  • Discovery of a brain-mapping technique to pinpoint epileptic seizures (1980s).
  • First successful larynx transplant (1998).
  • Discovery that damaged brain cells can regenerate (2008).
  • First U.S. near-total face transplant (2008).
  • Demonstration that bariatric surgery controls diabetes (2012).
  • World’s first deep brain stimulation surgery to restore function after stroke (2016).
  • First North American birth of a baby following deceased-donor uterine transplant (2019).

Lerner Research Institute

This institute is home to all laboratory-based, translational and clinical biomedical research at Cleveland Clinic. With 650,000 square feet of research space, more than 1,200 scientists and support personnel collaborate with clinical researchers to unravel the mysteries of disease.

In May 2002, Cleveland Clinic and Case Western Reserve University entered into a unique partnership to create a medical school dedicated to the teaching of physician-scientists. Cleveland Clinic Lerner College of Medicine of Case Western Reserve University combines education and research in an innovative program that mentors medical students to become physician-scientists.

Treatment Outcomes

Treatment Outcomes

Measurable Quality

Putting patients first demands a relentless focus on measurable quality. By setting standards, collecting data and analyzing results, Cleveland Clinic puts patients first through improved outcomes and better service, providing a healthier future for all.

Group Practice Model

Cleveland Clinic is structured as a group practice. The doctors on staff are salaried employees and are not in private practice. They pool their wisdom and expertise for the benefit of the patient and the community.

In 2007, we restructured our practice to complement the group practice model. By combining specialties surrounding a specific organ or disease system into integrated practice units called institutes, we can better provide collaborative, patient-centered care.

Clinical Expertise

Cleveland Clinic is organized by institutes, which align medical care in a way that is more easily understood by patients.
