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.

Every employee at Specialty Surgical Center is amazing. Dr Sunny Lo is the best, I had a colonoscopy and an endoscopy at the same time.

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.
