Robert S. Katz, MD is a Professor of Medicine at Rush Medical College and Northwestern 
University’s Feinberg School of Medicine and a leading expert in the field of Rheumatology, with experience in both research and patient care.
Dr. Katz was honored to be named in U.S. News & World Report’s Top Doctor rankings, considered to be among the top 1% of doctors in his specialty nationwide. Only 96 rheumatologists nationwide were selected to be one of America’s Top Doctors according to US News and World Report. In 2019, Dr. Katz was among 35 Physicians named Top Doctors by Rush.
Dr. Katz was chosen by Best Doctor’s to be included amongst the top 5% of US Physicians based upon an extensive, impartial peer-review survey that involved thousands of doctors nationwide. He was also selected as a Top Doctor in Chicago, by the International Association of Healthcare Professionals, and he was recognized in Chicago Magazine’s January 2020 issue as one of (494) top doctors in metro Chicago—chosen from the more than 40,000 medical doctors in the area. He has been cited in each issue of Chicago Magazine’s “Best Doctors” for more than a decade.
Dr. Katz received the Master Award from the American College of Rheumatology. This honor is the highest given by the ACR, to rheumatologists who have made significant contributions in the field. Only 22 physicians received this award worldwide.
Dr. Katz is Chairman of the Medical Advisory Board of the Lupus Society of Illinois. He is also a member of the board of directors of the Lupus Society of Illinois.
Dr. Katz brought together a group of researchers to change the criteria for the diagnosis 
of fibromyalgia, and they have been accepted by the American College of Rheumatology. Additionally, he has published more than 300 original studies and continues to participate in active research to discover the causes and treatment of a variety of diseases. For example, he was involved in research for new drugs to treat rheumatoid arthritis, including the first successful trial of a biologic medicine–Enbrel. He also participated in the clinical trial to achieve approval for the first lupus drug accepted by the FDA in over the last 50 years.
During a Congressional briefing, Dr. Katz shared his experiences treating patients with
lupus. “When you see a lupus patient who doesn’t look sick, it’s hard to imagine she suffers from a disease causing such fatigue and pain that she literally cannot make it to work or pick up her child from school,” Dr. Katz explained. “But behind that healthy face is an immune system run amok, attacking her own body at random. Striking any organ and tissue, lupus is a leading cause of heart attack, stroke and kidney disease among young women.”
About Rheumatology Associates
Rheumatology Associates, S.C., specializes in the diagnosis and treatment of lupus and rheumatoid arthritis. We also treat other rheumatic, autoimmune and related disorders such as fibromyalgia, ankylosing spondylitis, psoriatic arthritis, scleroderma, polymyositis and vasculitis. We treat low back pain, neck pain, shoulder problems, carpal tunnel syndrome, and other muscle and joint disorders.
Rheumatologists are nonsurgical musculoskeletal specialists. In a way, we are like cardiologists compared to cardiovascular surgeons, or neurologists compared to neurosurgeons. We specialize in diagnosis and conservative medical therapy, especially medication. We do not do surgery. When surgery is required, we will refer you to the proper specialist.
Our office includes X-ray, extremity MRI, ultrasound, an infusion room for intravenous medications and an in-house lab so that you can receive coordinated care in one place. Please let us know if you have any questions in scheduling your appointment.
