The NANI Success Story

NANI is the largest Nephrology practice in the United States and nationally recognized. For almost 50 years, NANI doctors have been leaders in Nephrology. Pioneers for our patients.

It was 1968 when the field of nephrology was just developing and the doctors who founded Nephrology Associates of Northern Illinois and Indiana (NANI) Just a few years later, Arthur Morris, MD and Paul Balter, MD joined the original founders, and they remain with NANI today. Since then, the group has grown to offer patient services from hospitals to physician offices and from labs to dialysis centers. We have added locations and doctors for our patients all around Chicago and northern Illinois, throughout northern and central Indiana, in New Jersey, and soon, in other states.

Our service offerings provide continuity of care for our patients. They include physician care for early stages of kidney disease, late-stage dialysis treatments, home dialysis training and support, pre- and post-transplant care, vascular access surgery and cutting-edge procedures, lab services, clinical research and close relationships with many patient support organizations. Today we honor our past but drive forward in the changing climate of Medicine, striving for excellence in patient care. We are proud to be leaders in Nephrology for our patients.

Patient Care Close to Home

In 1968, the founders of West Suburban Kidney Center (WSKC), Robert Muehrcke, M.D., Joseph Moles, M.D. and Arthur Gene Lawrence, M.D., created a new model for dialysis in Oak Park, Illinois that later became NANI. Their community dialysis centers were outside of the hospital, close to patients’ homes and in a safe medical environment. WSKC established the first mobile dialysis unit for Acute Kidney Disease patients staying at many area hospitals.

In 1976 NANI was formed and began hiring nephrologists to staff its growing number of dialysis centers in the Chicago area. Later that year, NANI established its first dialysis center in Indiana. Eventually, NANI physician offices opened all across northern Illinois, in the northern Indiana communities near Merrillville and Fort Wayne, in the Indianapolis area and in New Jersey. Our service offerings provide continuity of care for our patients.  They include physician care for early stages of kidney disease, late-stage treatments, pre- and post-transplant care, vascular access surgery, home dialysis training, lab services and support and close relationships with many patient support organizations.

As the largest U.S. nephrology practice, we maintain our leadership in the Field with our own clinical research arm, a professional consulting subsidiary, involvement in advocacy organizations and direct participation in federal quality of care programs.  We are proud to be leaders in Nephrology for our patients.
