Patient Comments (1)
in Miller Place, NY |
I was given a date & time which I wrote down in my daily planner. 5 days before my appt his receptionist call & told me I missed my appt. I explained I was told a different date & there was an honest mistake made by one the parties. I was told that "No Dr Greenwood does not make any acceptions for no shows". The woman was very snarky & had called me back 3 time to make sure she got me to say you can never be seen here!! A very cold & rigid policy for any MD to have especially a neurologist!!
