Procedure was smoothe, nurses and staff attentive and professional. I did, however, have issues with scheduling and pre day procedures. When I called to make an appt, I got a service. They took the info and told me I’d get a call from the scheduler. I never got a call. I called again, informed I hadn’t rcvd a callback, and was put through and scheduled. I was told I’d rcvd an email with instructions. Never received so I had to call again day before procedure for instructions. Then they sent the email. Lastly, post procedure they asked if I wanted a snack but then said they had run out.

From the time I walked into the facility to the time I left was extremely satisfied. The nurses were very nice and I felt very comfortable with them. My anesthesiologist was great. Of courses Dr Rosenthal is wonderful. Thanks to everyone for a wonderful experience.
