About me

Dr. Nathan Karp is a rheumatologist who cares for patients with a range of autoimmune and musculoskeletal conditions. He has special interests in diagnosing and managing types of inflammatory arthritis (such as rheumatoid arthritis, psoriatic arthritis and gout), myositis (conditions involving inflamed and weak muscles), vasculitis (inflammation of blood vessels) and lupus. He is passionate about clear and open communication with patients and believes that shared decision-making between providers and patients is particularly critical in his field. In addition to caring for patients, he directs quality improvement for the rheumatology clinics and teaches medical students, residents and fellows.

At UCSF, Karp earned his medical degree, completed a residency in internal medicine and completed a fellowship in rheumatology.

      Dr. Karp Iwas very compassionate regarding my illnesses. Listened, ask questions and then explained what he thought might be going on. He acknowledge some medication that had been descripted by another Dr., that was not appropriate for me to take. I had waited to discuss this with him. He would look at all my lab work that had not been received (although it had been requested by me to him) and would let me know. I received his summary and will follow his advice. I am so happy I found UCSF Care Team.
