What is a Rheumatologist?
A rheumatologist is a physician who is qualified, by additional training and experience in the diagnosis and treatment of arthritis and other diseases of the joints, muscles and bones. After four years of medical school and three years of training in internal medicine, rheumatologists devote an additional two to three years in specialized rheumatology training.

- DMCantuDr. Ayala is treating me for dermatomyositis. She has been a lifesaver. (Literally) I was in constant pain before she added a second medication to my treatment. My quality of life has increased exponentially. I’m so grateful.
""
- JeremyDr. Moorjani is always willing to answer questions and takes his time addressing my concerns. He met with me, and worked with my changing insurance in order to get tests run that I needed in a specific timeframe. He listens to my concerns and his staff is kind and answers phone calls and questions quickly. I recommend Dr. Moorjani as he seems up-to-date in his knowledge of his specialty, and his compassionate manner is comforting when facing a scary diagnosis!

- AdrianaI cannot say enough great things about Dr. Marx & her asst Crystal . She’s amazing, caring and actually LISTENS. You dont feel like your being “timed”. I refer everyone and anyone to her. If there’s a will, she will find a way!

- B ParsonsIf I could give Dr Allen 10 stars I would! New patient visit was 45 minutes long (which is unheard of), personal, great listener, and just a great overall guy. He offered reassurance, guidance, and explained at a level that was easy to understand. It was worth the wait for this appointment! Office staff was also A+!

- AnnI was diagnosed with Lupus about 3 years ago. I bounced from doctor to doctor until I finally landed here at RAST. I absolutely love and have full confidence in Dr. Moorjani. He is not afraid to try new treatments, really spends time listening to me, and just doesn’t offer me the company line. It was he who actually figured out I’m one of the lucky patients who has both Lupus and RA. Every other doctor I went to just put me on the standard protocol for Lupus. I have given Dr. Moorjani’s name and number to many of my friends who are looking for a Rheumatologist.

- KimDr Kevin Kempf is the most caring, compassionate and knowledgable rheumatologist I’ve ever met!! I’ve been blessed to call him my dr for over 10yrs!!! He takes the time to listen to me, answer my questions and even give me things to read on my own because he knows I’m always looking to better my health. I couldn’t ask for a better rheumatologist, office staff, infusion nurses, etc. They’re ALL wonderful!!!

- ArtVery pleased. I would definitely recommend Dr. Kempf and his staff to anyone suffering from arthritis. They are very professional, efficient and have a great talent for communicating with you in a caring manner.

- LynneDr. Rennie is knowledgeable, through and very easy to talk to. He also sees patients at their appointment time, not hours late like my previous Rheumatologist. I was referred to Dr. Rennie by another doctor when I wasn’t happy with the previous Rheumatologist I was seeing. He is a 100% improvement.
