Rheumatoid Arthritis Doesn't Wait Months to See You.

Neither Should Your Rheumatologist.

Do your doctors treat your RA like an emergency?

They should. Because wasted time = more pain.

More bad days than good. It hurts just to get out of bed. You worry about showing up for your job, your family, your friends. And every day that passes means more suffering.

No one deserves this—especially when rapid improvement is within reach.

"The best rheumatologist in Orange County."

After four months spent visiting 26 different physicians, multiple labs, CAT scans and MRIs, I found Dr. Girnita who immediately recognized my autoimmune condition and started me on a treatment plan that respected my wishes. I am sorry I didn’t find her sooner.

~Lin Crampton

Dr. Girnita is amazing! I had severe health problems, after seeing several practitioners who didn’t listen to me or understand my concerns. She was very patient, provided detailed explanations, ran thorough labs and her treatments were helpful. I felt heard & cared for.
