I had a colonoscopy today at the Fern Hill location. The staff was great throughout the whole process, from signing in to leaving the facility. They also gave me some very helpful information. Dr. Hwang was very professional and comforting. I was very happy with this practice and would recommend it to anyone who needs this procedure done. It's not a very pleasant thing to do, but it's very important, and the staff at West Chester Endoscopy made it much more pleasant. Thanks to all the folks involved in my procedure for their genuine concern for my health. I am home and feeling good.
