About me

  • Assistant Professor of Clinical Medicine (Rheumatology)

I am a rheumatologist with clinical expertise is in spondyloarthritis, a group of diseases including psoriatic arthritis, axial spondyloarthritis (also known as ankylosing spondylitis), reactive arthritis, and others. My specific focus is axial spondyloarthritis and IBD-associated arthritis. My research has focused on the use of patient-reported outcomes to improve understanding of the patient experience of rheumatologic disease. I also serve as Penn Rheumatology’s Vice Chief of Clinical Affairs, a role in which I hope to improve patient access to rheumatologic care and to improve delivery of this care in a fragmented health system. I have a passion for advocacy, and have been active in advocacy efforts at the federal level. I spend my free time (such as it is) gardening, birding, hiking, and trying my best to keep up with 3 young children.

dr. craig is a wonderful doctor and, listen to you when you during your visits. he has been treating my arthritis for the past several years and, was instrumental in getting some testing done on me that no one else did. also dr. craig and, my dermatologist collaborated on what medication would be best to use on my treatment. i will miss him.
