Dr. Siu is a blessing to his patients. The Florham Park facility is amazing--a rare blend of efficiency and compassion. The staff is expert at what they do. It is a pleasure to watch them work, and very reassuring as a patient. Dr. Sood was caring, friendly and did a great job, I am very much less impressed with scheduling staff. Frankly, I am amazed that they have 't killed anyone. Simultaneously I received confirmations of my tests being in both Hanover and Florham Park. I had booked both an endoscopy and a colonoscopy but confirmation came for only the later. Almost to my arrival, staff kept telling me it was only the colonoscopy. Unnecessary confusion and stress. My first booking, for an endoscopy was scheduled and confirmed by email, for 8:30 arrival/9:30 procedure in Hanover on April 14. As we were arriving at the building I received a call from the center that my schedule was to arrive at 8 for a 9AM procedure. They showed me their print out of the schedule. I showed them my email But a patient starts to become worried by even small errors. The coup de grace was in having to postpone the procedure The prep instructions sent to me were a 'very old" form. They did not reference Ozempic or similar meds (form predated their use). I followed all the instructions to the letter but had no knowledge of the need to hold that drug for 8 days prior to the procedure. Had to reschedule. Dr. Siu apologized many times. But he should not have to. He plays his role expertly. He deserves better support. As do his patients. Please review staff training and performance. Even the colonoscopy prep instructions include a typing error that could result in cancelled tests. See page 2 where there should be 2 columns showing what can and cannot be eaten on prep day. In the middle of the list a missing indent left an important element in between both columns. Silly, unnecessary errors that erode patient confidence Please proofread. Thank you.
