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

Beat the Trend of Early-onset Colon Cancer through Timely Screening
Colorectal cancer cases rising in young adults is a concerning global trend. The best way to beat the trend is to prevent or detect the disease early through timely screenings.
I would and will highly recommend Dr. Yvette Lam. My first routine colonoscopy could not have gone better. Everyone I spoke to was genuinely caring and wanted me to feel confident that everything was going to be ok. Because, let's be honest, I was not feeling very calm about this whole thing. The minute I met Dr. Lam and her team, all of that worry and anxiety melted away. I knew that they would take the best care of me possible and when I woke up, I was reassured that all went well. I had no complications the rest of the day.
