    This entire experience has been eye opening. I have never felt so abandoned by a medical team. God forbid there was something more serious on my ECHO. Given that it took three weeks to speak with anyone from the team despite almost daily requests to talk to me this seems like a highly risky department failure that should be further investigated by a QI committee. The fact that there was no explanation offered as to why this error and dereliction of care took place is honestly infuriating.

    Phoned me the following day after discussing (my somewhat complicated) case with other specialists; greatly appreciated.

    White doctor coat worn by this provider was badly soiled and in need of laundering. A clean professional appearance should be part of the job.
