I've been going to Dr. Mann at Guilford Endoscopy Center for years and recently had my 3rd colonoscopy. The entire experience is very organized, the staff are all highly professional and friendly, from check-in to check out. The nurses do their jobs very well and make me feel comfortable in their care. Dr. Mann is extremely efficient and she always lets me know what, if anything, she found and removed during the procedure. I feel like I'm in great hands with her as my doctor and all of her support staff are super at their jobs as well. I'd highly recommend Dr. Mann, get your colonoscopy!
