Dr Feinberg is great - always feel like he is guiding me on the right track. I was very frustrated with the fact that I showed up for my appointment on time, brought in to my room and then had to sit in my underwear for 30 minutes while I waited for the exam - at the very least, the assistant could have told me that he was running late or that there was going to be a delay. This is incredibly inconsiderate and unprofessional.
