I lived in Dallas for 8 years. Dr. Royappa ROCKS. She knows what she’s doing, and she cares about her patients. She is VERY smart, and is a superb internist/family doctor. She studied Physics, and later went to medical school, so that outta tell you how smart and dedicated she is. She communicates very well with her patients, and has a tremendous amount of compassion. Her staff is also very professional and caring. I loved all of them, and now that I have moved to San Fran, I miss this office and team a lot. If you need a doctor of internal medicine… don’t go anywhere else. Make this your office. You won’t be disappointed.
