Cotton O’Neil

Primary Medical Care. Specialty Services for Kansans.

Cotton O’Neil, a part of Stormont Vail Health, provides primary and specialty medical care to many northeast Kansans through clinics in Topeka and other northeast Kansas communities.

The clinic started in 1956, when Drs. Robert Cotton and Robert O’Neil created a joint internal medicine practice near Stormont Vail Hospital. In 1995, the clinic had 74 physicians, many of them specialty physicians, and it merged with Stormont Vail Regional Health Center to become the medical service division of the hospital. The clinic maintained its name and functions to this day as a multispecialty physicians group.

Cotton O’Neil has evolved and grown over the years to become one of the largest primary care clinics in the Midwest. People from across Kansas receive primary care and specialized services through the clinic. Specialty physicians also provide outreach clinics in several communities around northeast Kansas. Some specialty physicians also make use of telemedicine to care for patients living in western Kansas. 

Most recently, Cotton O’Neil has been successful in recruiting a variety of pediatric specialty physicians in areas like hematology/oncology and diabetes. These physicians make it possible to provide care across the state and beyond. Families in northeast Kansas can count on Cotton O’Neil for health care that continues to meet their needs.

Our vision for the future of health care remains optimistic and physicians and staff are proud to be a part of one of the most successful integrated health systems in the United States.
