I scheduled an appointment with Dr. Shannon to have an EGD procedure performed for an upcoming surgery with another surgeon. However, when I arrived for my appointment I was told that I had been given the wrong time and date, Dr. Shannon was in surgery. Therefore, I was asked and given a time to return later that day, when his surgery clinic had ended. When I returned, I waited over 30 minutes before I was called into an exam room. Once I finally was put into an exam room, his nurse had updated

Outstanding Doctor! He makes you feel very comfortable and knowledgeable. He doesn't make you feel like you are being rushed and he answers your questions thoroughly. His bedside matters are excellent, he explains his procedures and his findings. I didn't feel like a doctor payment but like an actual patient. His staff was also polite and helpful.

From the moment we walked into Dr. Shannon's I was impressed. The staff was very caring. Dr. Shannon himself was great. Asked questions and listened to my sons answers. We walked out of his office feeling very at ease.

Scheduling nightmare.Started in Dec.2015 saw him Jan13th 2016 Dr. Shannon ordered colonoscopy before even seeing me. Haven't even talked to him yet about the problem I was having. I saw Dr. Shannon for every bit of three minutes. No exam just told me that I was close to 50 and he could give me a colonoscopy to see what was going on.Gave me meds for something he has no idea could be the problem. Colonoscopy set for Feb.2nd. insurance problems with OakBend had to reset for March 3rd. Not happening
