Dr. Kozlowski's bio

This content was provided by Dr. Kozlowski "Having grown up in a family that was ravaged by severe arthritis, I became very interested early in life in the diagnosis and treatment of severe arthritis. Therefore, I pursued a career in Rheumatology. During my training at Northwestern I was involved in clinical research in Rheumatoid Arthritis, Osteoarthritis, and Ankylosing Spondylitis; as well as scientific research in immunology especially as related to Systemic Lupus. My career has been dedicated to the compassionate diagnosis and treatment of all rheumatic diseases and conditions. I have enjoyed teaching patients, students, residents, fellows and colleagues about the broad field of Rheumatology throughout my career. And I am very grateful for the opportunity to be able to pursue these endeavors now and in the future. "

Care Philosophy

This content was provided by Dr. Kozlowski "     My philosophy of practice centers around trying to make the patient feel comfortable to share their medical history and to describe their problem in as much detail as necessary. It is important for the patient and I to develop a therapeutic relationship. I believe that my role as a specialist in rheumatology is to listen closely to what my patients are telling me, to examine them, and to order whatever testing may be needed to make the correct diagnosis. I explain to the patient the reason for ordering the tests, and I take into account the patient's concerns.

In the beginning it seemed Dr. Kozlowski was genuinely concerned about his patients but with the overflow of new patients he has received it seems he has turned into a more get-you-in, get-you-out kind of doctor.

This comment is absolutely untrue. Ask any other of my patients and ask my staff. I rush no one! I sit down and engage all my patients in dialogue at length about their conditions. At the end of the visit I ask the patient if they have any other questions or concerns, and we discuss those as well.
