I am a board-certified rheumatologist who provides consultative care for patients with a wide variety of musculoskeletal and autoimmune diseases. My training and experience have provided me with the ability to evaluate and treat complex illnesses and work closely with your primary care provider to achieve the best possible outcomes. In addition to patient care, I spend about half of my time doing clinical research. Throughout my research career, I have focused on the development of novel therapies for various rheumatologic diseases, including primary Sjögren’s syndrome, vasculitis, and rheumatoid arthritis. As a leader within the Division of Rheumatology and Immunology, I have gained an appreciation for the value of teamwork in addressing patient concerns and improving our clinical practice. I balance my job through family and sports, which keeps me energized and happy with my work. Dr. William is rated as an Advanced provider by MediFind in the treatment of IgG4-Related Disease.
