The entire procedure was not what I had expected. Dr. Dever and his entire team were phenomenal . To have a colonoscopy is quiet invasive, especially for us older folks. They are all so kind and respectful. They took the fear totally out of it. Would like to say thank you again.

My husband and I couldn’t be more satisfied! Dr Dever is a high quality physician all the way around! We saw him several yrs ago when he was with Saltzer. We found him again at IGA! We are very confident in his abilities as a surgeon etc. So thankful we found him again!

This was the the most uneventful colonoscopy I have had to date even though my colon was not completely evacuated. Both Dr. Dever and his staff were professional and efficient with no time wasted. Thanks to the doctor and his staff and I hope I have have the same group next time.

Well, what can I say, but it is SOOO nice to make your patients feel COMFORTABLE in EVERY way: experience/knowledge, professionalism, friendly, calming and concerned with your well-being!!! That goes from the front desk (sorry, but I forgot the young man's name), to Carrie who got me ready for the procedure, to the anesthesiologist to the main man, Dr. Dever himself. ALL A+ in their fields. SERIOUSLY. Thank you ALL for taking good care of me!
