About

At Rheumatologix, Dr. Tonya Baker delivers direct-pay rheumatology care to patients across Eastern Tennessee. She founded the Knoxville practice with one clear goal: restore the one-on-one connection between physician and patient. Her guiding philosophy treats the whole person, not just the diagnosis.

Dr. Baker holds double board certification in internal medicine and rheumatology. She limits her panel to 400 patients, allowing her to spend genuine time with each one. First visits run 90 minutes, starting with a 60-minute consultation and a 30-minute physical exam. The practice draws labs and dispenses many medications in-house. Dr. Baker also brings a background as a personal trainer, incorporating diet, nutrition, physical training, and stress management into care plans. Rheumatologix treats rheumatoid arthritis, psoriatic arthritis, psoriasis, lupus, fibromyalgia, and COVID vaccine response. Patients who need a specialist typically wait 6 to 12 months in Eastern Tennessee; Rheumatologix schedules within days.
