This will be my second procedure with Dr. Sunny Lo. The first one was almost four years ago, everything went well and great results. Now that it is time for a new procedure it only made sense to come back to him, so needles to saShow morey I expect all to go well and will be a normal procedure. We have got to take control of our health issues and it is always good to count with the right Doctors that we can thrust with our health needs.

Dr. Lo analyzed and explained my medical condition to me in great detail, and immediately scheduled a colonoscopy for the near future. This made me feel very reassured, and my family felt relieved as well.

I had an excellent experience with Dr. Sunny Lo. He is highly compassionate and ensures you feel completely comfortable during your visit. What stood out most was his personalized approach to care. He genuinely listens and treats you as an individual, not just another patient in a busy office.

Lucie S • March 19, 2026

I went for a colonoscopy. The Specialty Medical Center from which Dr. Lo works is an oasis in the wilderness of health care; personalized & efficient. The day before the procedure, I got a call from the very nurse who was in the OR during my procedure. So when I met her in pre-op it creating a feeling of familiarity & connection. The intake nurse went over my chart expertly & cheerfully did the pre-op as did the OR nurse & the anesthesiologist. Delay of procedure is the only complaint.
