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. K demonstrated very excellent skills and some not experienced from past providers. Is this training from UCSF program or himself, very interesting to see these differences in care providers. Still had to ask good questions though.

      Dr. KARP was amazing! He took his time, listen to me, really tried to understand what's going on with my complicated history, had great bedside manner, was very knowledgeable and personable. Incredible experience! I can't speak highly enough of this doctor. I'm so excited. I got into him and that he will continue with my care. He really seems like he's going to go above and beyond to finally sort out what's going on with me. I've been to three other Rheumatologist, who never could do so. He came up with super creative ways to diagnose me. He also cared about wasting my time by scheduling a follow up call over zoom versus having me drive an hour to get to his clinic. I really appreciated that as well.
