Very caring and explains everything
Dr Sandler is well educated in his field. He spends extra time with his patients, if needed. I don't say this about every physician, but he is a professional doctor. I would recommend him to anyone needing a cardiologist.
My only grip is I got there at 2 o’clock my appointment time , and I finally saw the doctor 3:10 . Dr. Sandler is great.!
