This jerk lied to me when he told me that the colonoscopy he was about to perform would be, at the most, "A little uncomfortable." He said it 4 times. Total bull. This proceedure is painful. Level 3 to 5 painful. So Iwata is either stupid, or a liar. Either way, don't trust this liar. He also lied about the seriously negative effect the colonoscopy would have on my hemorrhoids. He ignored my concerns and caused me significant pain & suffering. It took 4 more painful proceedures to fix.
in Colorado Springs, CO |
Dr Iwata was very thorough in ascertaining my needs for requesting the tests that my primary physician ordered. He then was able to share with me his opinions on my needs and discuss with me his reasoning and best practices. He listened well and was not hurried during the consult . My questions were respected and given thoughtful replies. Ultimately I felt very confident about the decisions reached and my impending procedure.

I have been seeing Dr. Iwata for many years. He is the only one I would trust with my gastro health, and I'm not kidding. Over the years I have observed his dedicated approach to his craft and have been impressed with him at every visit. I have always found him to be friendly, cordial, and very professional. I believe I do not have colon cancer today because of the care and advice I have been given by Dr. Iwata and his staff. He and his organization come highly recommended.

Digestive issues can be very confusing, scary and PAINFULL for us patients. My prior GI labeled all my issues as Gastroparesis and sent me on my way to fend for myself. Dr. Iwata listened to me when I was describing my symptoms and is helping me dig deeper to get some relief from my major issues. I really appreciate all of his years of experience and him helping me to improve my quality of life.

I've had the pleasure of being treated by Dr Iwata and his team twice (2013 and 2016). No problems, very responsive and Knowledgeable. I will use Dr Iwata again in four years without hesitation. I have and will continue to refer his excellent service to family and acquaintances. Thank you Dr Iwata.
in Colorado Springs, CO |
I was very disappointed with the staff and Dr. Iwata. My phone calls were not returned. Wait times of 30 and 40 minutes were routine. Dr. Iwata seemed annoyed and distracted. He didn't really answer our questions honestly, or he didn't know what he was talking about. We will never return.
We are very sorry you had a bad experience. If you would like to discuss this further please feel free to call our office and ask for the practice administrator as she is always looking for feedback and ways to improve in any way.

My experience with Dr. Iwata and his staff was very positive. I just retired from a career in healthcare so I am familiar with the way a clinic should be run and I was pleasantly impressed. My wait time was not long and the staff was friendly and helpful. The prep procedure was not as bad with this colonoscopy as it was with the one I had 10+ years ago.
