Directions posted within the hospital to find room 550 are non existent. Room 500/530 are in a totally different area requiring both a serious walk distance, and questioning an office clerk to tell me how to get to 550. And easy one to solve - add 550 to the signage a both end of the hospital. This was a considerable irritant.

I was prescribed two medications. One was only called in the other one. I called and it was supposed to be called in the next day. It never was. I'm still waiting on the prescription to be called into the pharmacy after 3 days.

Wonderful staff

Mary Greco was very thorough and efficient and reviewed my medicines and treatments. Based upon my overcoming trigeminal neuralgia, she recommended tapering me off my two remaining nerve meds. Together we decided on just starting with one of the meds. She said if I had any issues I was to contact her immediately. She is very personably as well.
