I’m older and not interested in confusion these days. Just want to get it done. Everything went well with my colonoscopy. Waiting area wasn’t packed full of patients like most offices are. There wasn’t page after page of repeated information to fill out for the tenth time. The front desk staff was very pleasant and knew what needed to be done quickly. Front waiting time was very short. Didn’t need to bring a book or phone cause there was no time to look at either one. No confusion in the back clinic area. Staff appeared to know what their job was and had personal information about me and made sure there were no changes that needed updated. Anesthesiologist had information on how well I handled anesthesia in the past and informed me of how it would go this time. Seen the doctor before the colonoscopy and after waking up. Doctor made sure I understood what was found or not found before I left the clinic. Staff made sure I had a ride home with someone responsible. My time at this clinic was definitely stress free.

You created an undesirable experience into an easier than expected procedure. The whole staff could not have been better. Their easy and cheerful dispositions brought forth a calming and professional care. You knew you were in “good hands”. Thank you Dr. Lam and all of the Sun City Endoscopy staff. I recommend to all who are especially undecided about moving forward to this recommended test to use SunCity Endoscopy Center. Debbie D
