Awesome! Wow, what an excellent experience for the procedure. The facility was great as well! Everyone was friendly and professional. Scheduling was a little rough, everything is done on line and through email. Combing through the junk emails I missed the prep email. I called the office, then texted and got a script called to the pharmacy within the hour and filled right away. I made the prep timeline perfectly.
Had an overdue follow up Colonoscopy here and my experience was a great one! From check in, to being taken back and prepared for the procedure including an overview of discharge directions, the procedure (which of course I don’t remember), and postoperative area. All staff and physicians were wonderful and available for questions. Definitely recommend this facility and Dr. Brenner!
