Why RheumWorld™?
We built RheumWorld™ because rheumatology learning should be clear, not confusing. Fellows use our questions to prepare for boards. Attendings use them to stay current. Residents and advanced practice providers use them to go deeper into the specialty. Everything we publish is written to build real understanding, not just test recall.

Built by a Rheumatologist
RheumWorld™ was founded by Mario David Felix, MD, MHS, a board-certified rheumatologist who writes every question in the bank. He started the company because the resource he wanted as a fellow did not exist, so he built it.
