I have been treated by Dr. Iwata for two different procedures, an upper GI series and 3 colonoscopies over a ten year period. I have the utmost confidence in his skills and would not consider using any other provider for these type of procedures. His manner is very friendly and professional. He explains what he is going to do and is extremely efficient at delivering those services. He visits before and after the procedure to explain preliminary results.

Dr Iwata is simply the best doctor I have ever seen. When every other doctor was telling me the only hope for me was to remove my colon, Dr. Iwata worked very patiently with the newest technology. I always credit him with saving my life.

Very friendly and welcoming. Office staff exceptional. They even provide espresso drinks once you wake up to help with caffeine withdrawals during prep... Under the menu label of "bottoms up cafe."
