One of the worst doctors I've ever encountered. Save your time and money and go elsewhere. Waited ~2 hours past my appointment time to see the doctor for only a few minutes. He paid more attention to the student there that day, lamenting that I didn't have an ear infection for him to show off. He didn't listen or seem to understand why I was there -- just said I needed a CT scan before he could do anything and rushed me out. He mentioned nothing about examining via scope (which I'm familiar with from having been to other ENTs and even the office staff told me to expect) and offered absolutely no help for or even acknowledgement of my severe sinus pain.
Dr Sandler was very thorough, answered all my questions and has been readily available for me whenever I have called. He discussed all of my options for treatment and let me make my own decision based on my particular situation. I highly recommend him.
