Doctor and Patient

Our Patients are Our Priority

Our doctors and staff care for people with kidney disease, kidney injury and difficult to control hypertension.

Nephrology Associates of Northern Illinois/Indiana (NANI) is focused on the patient care experience. Not only do we ensure the best care available but we consider the patient’s total experience from scheduling, office locations, and communication to a comprehensive care plan for each patient.

You will meet with your NANI doctor in a familiar medical office with the confidence that comes from knowing that he is part of a nationally recognized medical group. NANI is always adding patient services for better and more convenient treatment. We stay on the cutting edge of new clinical research techniques and the best patient protocols.

Leaders in Kidney Care

Since 1976, NANI has provided experience, innovation and reliability in kidney disease and blood pressure management.

Today, in addition to our growing network of medical offices and dialysis centers, NANI has expanded to include other services our patients might need. Vascular centers for outpatient procedures, diagnostic labs and high blood pressure specialty centers are within reach. NANI doctors are always on the forefront of new treatments and cures. Interventional nephrologists have joined the team so we can coordinate the best care for our patients from office visits to outpatient vascular access procedures to dialysis care.
