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.
