Hi! This was my first experience with the Colonoscopy procedure. Everything went really well over all. From start to finish, took about 40-45 minutes. Unless you have the people that have lots of removal of polyps, then you’ve lonShow moreger wait. Overall, I have to give a 10 for my scores, it was an excellent experience for me. I have a team of caring nurses and doctors. Thank you Dr. Lo , Dr. Laurel, and the amazing team of nurses from Arcadia USC Hospital!!

Great doctor. Knowledgeable, skillful, patient, caring and supportive. Always take time to answer your questions and concerns. Front office staffs are pleasant and helpful. The wait could be very long at times but so is the appoiShow morentment made with other doctors. In short, Dr. Lo is an amazing GI physician and in my opinion, one of the best in the area and definitely worth the wait.

Jingjing Z • January 17, 2026

Interesting. I went to the Alhambra location for a colonoscopy. They kept on profiling me for Chinese. The amount of time for the intake and starting IV was short, but then a long wait. I think I got the end position due to my language and class appearance. Then into the ready room and onto my table. They again thought Chinese speaker, but realizing my English preference they put me in the side of that room too. Finally, they seemed to put me in the hallway. Easy process. Good on anesthesia.

Myron Q • January 16, 2026

The staff at Concourse Diagnostic Center were nice, friendly and somewhat efficient. After I was prepped, I waited for quite a while before I was wheeled to the corridor where it was colder and had to ask for an extra blanket. Waited there for another more 35 minutes before the procedure. Perhaps too many patients all at once and ran out of room. Afterwards, they let me go without the reports. I was outside the car park when I was asked to go back for them.
