About Saint Louis Rheumatology

Saint Louis Rheumatology specializes in the diagnosis and treatment of rheumatic and autoimmune diseases. We also focus on researching a wide variety of autoimmune and rheumatologic diseases, including rheumatoid arthritis, lupus, psoriatic arthritis and many others.  We work closely with other health care professionals in assisting patients who require additional services to treat their conditions.

Chad Ronholm, M.D. and Joseph A Stauber, M.D. are board-certified rheumatologists with extensive experience testing for and treating autoimmune conditions.

At Saint Louis Rheumatology , every patient is paired with their own medical team consisting of a physician assistant and a rheumatologist.  The team works together combining physical examinations, medical history, sophisticated immunologic and imaging tests  to achieve an accurate diagnosis in the most efficient and effective manner.
