Thank God I only need a colonoscopy every 5 years because that's plenty of time to find a new gastroenterologist and affiliated medical center. My first introduction to Endoscopy Center of Ocala was a women named Lisa who called herself a nurse. I think Lisa's house was on fire because she was in such a rush to get home. She asked me questions while she had me chase after her from room to room to change, go to the bathroom and lie down. She was in such a hurry that she even told me to finish changing while I was in the bathroom. When it came time to stick the needle in my arm I asked if we could take a breath and slow down. Oh boy did that set her off. She couldn't believe I asked her to be careful. She claimed she wasn't rushing and this was her normal pace. She then proceeded to stick me causing more pain then needed (see photo for bruise). After leaving my room she went to her comrades at the nurse's station to complain about me. The facility is a cramped tiny area so I could hear every word. I even yelled that I could hear her but the 90s music playing loudly over the speakers drowned me out (added to the loud music is someone at the station singing badly over it). I could hear her clearly as she ran around saying good-bye to everyone, giving instructions as she ran out of there. So not only are you feeling gross because you've been doing the cleanse and pooping out your insides, but you are treated like an object on an assembly line by thoughtless people who are supposed to uphold ethical standards and dedicate themselves to patient care. After Road Runner Lisa left, I thought it was going to be all uphill. I was wheeled out of one tiny room to another which can hardly be called an operating area. In passing I noticed a small closet with a glass door containing what looked like black rubber hoses hanging. I was ready to get up and make tire marks like Lisa out the door. Unfortunately, I didn't have time because a foot from the hose door was the procedure room door. Before I knew it, I was greeted by the anesthesiologist and nurse. Off in the corner, a few feet from me, was Dr. Pastorini in street clothes munching on a snack bar as she looked at the computer screen with records from my last colonoscopy. She did not greet me or say anything to me. I was grateful the anesthesiologist showed some professionalism and decorum. I prayed and hoped for the best. A few days later, I received my results via Quest Laboratory. I waited a few days giving Dr. Pastorini some time to read the results and respond with a plan. I then called and left a message asking for the doctor to call me. Two days later I heard from a nurse from the doctor's office. She was very nice and tried to answer my questions but was obviously reading from a script. If you have low expectations, this place will be fine for you. Having been cared for by the best doctors and receiving first class medical care, I cannot recommend this place. Be like Lisa -- RUN!!

Sure. A colonoscopy isn't going to be a pleasant experience. But the folks at Raleigh Endoscopy made mine as pleasant as possible. Everyone was friendly and informative.
