Stay as far away from this place as you possibly can! I was forced to go there this week to have a virtual colonoscopy because I am no longer a candidate for a routine procedure of this sort. There were two technicians working with me to insert a 3" enema tube into my rectum and then do a colonoscopy using a CAT scan type of machine. After three attempts and absolute pain on my part, they inserted the tube and both asked me, "it's in; do you feel it in your rectum, or is it inside your vagina?" I was flabbergasted and told them that as technicians, they should have a pretty good idea as to where the tube ended up. I will never, ever use their services again in the future. If you need a virtual colonoscopy and find, as I did, that only Steinberg does them in Las Vegas, NV, hop a plane to a California hospital and have it done there. This was the biggest joke - and no one was laughing, especially me! Can't wait to tell my gastro doc about this hideous experience!
