Offering Cutting-Edge Rheumatology Healthcare
Medical Specialists of Johnson City (MSJC) physicians are dedicated to providing compassionate care. We are part of State of Franklin Healthcare Associates (SoFHA), a progressive, patient-centered system of medical practices serving Northeast Tennessee, Southwest Virginia, and Western North Carolina.
Our rheumatologists are trained to identify and treat the causes of musculoskeletal pain and swelling, including autoimmune connective tissue disorders. Arthritis, gout, and ankylosing spondylitis are just three of the more than 100 types of rheumatic diseases.
You don’t have to be affiliated with SoFHA to use our sub-specialty services. However, if you already see another SoFHA physician, we have access to your medical records, making your visit more efficient and effective. We also offer FollowMyHealth® Patient Portal, a secure, online application through which you can keep track of your own progress and medical history.
Up-to-Date Medical Technology and Treatments
Our physicians are board certified in their respective specialties and keep abreast of all new research and treatment practices, such as using immune modulation therapies in addressing rheumatic. As part of SoFHA, we also have easy access to a variety of services, including a lab, physical therapy services, an imaging department, plus walk-in and diabetes clinics.
On occasion, our patients need “infusion therapy” or intravenous (IV) therapy when medications may cause unpleasant side effects if ingested or are too large to be taken orally. Our infusion suite is conveniently located next door to MSJC in a special Acute Care Clinic (in same building with Johnson City Internal Medicine), also operated by State of Franklin Healthcare Associates. Staffed with an experienced medical team, this clinic provides a private, comfortable environment for receiving infusion therapy, which may require as little as 15-30 minutes or last as long as 4-5 hours.
Types of conditions our rheumatologists treat:
- Rheumatoid arthritis
- Systemic lupus

Arrival Times and Cancellations
Medical Specialists of Johnson City strives to provide excellent, quality care to every patient in a timely manner. In an effort to provide care when you need it, we have updated our policies on missed or canceled appointments and patient discharges. We try to be good stewards of your time and ours.
- Please notify us as soon as possible and at least 24 hours in advance when you are unable to keep your appointment. In addition, we need time to greet you and complete registration for your appointment. Therefore, we ask that:
- Established patients arrive at least 15 minutes prior to your appointment. Should you be running later than 15 minutes past your appointment time, we may consider this a “no show” but will make an effort to see you.
- New patients arrive 1 hour early to register and complete paperwork. If you have already completed your paperwork please arrive 45 minutes early.
We never want to say goodbye to a patient, but sometimes circumstances cause us to determine our relationship isn’t working the way it should. If you miss or “no show” appointments three times, you are not receiving the frequency of care you need nor are we able to use that time for another patient in need. At that point, you will be asked to establish with another provider for your care.
