Very professional and attentive. Nurses lead you through final prep for your procedure, accompany you to procedure room. Both doctor and anesthesio logist visit before procedure to make sure you understand what will happen. Each nurse/doctor ask you questions to make sure all potential issues are covered: identity, medecines you take, allergies, etc. Friendly and polite and a warm blanket!

You're Not Too Young: Why Colon Cancer Screening Matters
Colorectal cancer is increasingly affecting adults under 50, making it a growing concern among younger populations.
Dr. Kothur is prompt, and answers all questions in a polite and professional manner. When I had a slight complication after my first colonoscopy, he personally called me every evening to make sure I was improving. This level of care and concern is not often seen, and I appreciated his thoroughness and involvement. The staff at the endoscopy clinic is top-notch: kind, informative and pleasant.
