Patient Comments (2)

Dr Horowitz is thorough, professional and companionate. She listened to my daughter’s concerns. We’ve had many rheumatologists and are very happy with our decision to stay with Dr. Horowitz.

I saw the doctor for almost a year, she was unable to make the correct diagnosis within that time. I went to another doctor and he made the correct diagnosis within the first 10 minutes of my first visit. In my opinion, Dr. Horowitz borders on incompetent.
