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!

My colonoscopy was in January, my insurance company is still fighting with their billing department here to code my procedure correctly. I’ve been billed for a preventative procedure which should be 100% covered. Be warned ya’ll ☹️

I experienced some of the best care I have ever had with Sun City Endoscopy. Everyone was thorough and explained everything clearly. They had a sense of humor too. I highly recommend them to anyone in need of their expertise.

The Sun City Endoscopy Center provided a safe and professional environment for my colonoscopy. The staff and Dr. Lam were great and made me feel at ease. I would highly recommend them for your GI procedures.
