"Dr. Wendorf and his staff were outstanding... For anyone who knows, IYKYK - this is an unpleasant situation/procedure for anyone that goes in for a colonoscopy. The prep was clearly explained. This was the worst part of the whole ordeal... The follow up prior to the experience was fantastic. The check in was quick, and they have more than one restroom for those of us that still needed it frequently prior to the procedure. From the nurses to the anesthesiologist to the Doctor himself were all extremely helpful and thorough in explanation from start to finish. This is a very fine tuned machine indeed. They made an unpleasant procedure a breeze, and I would recommend this facility to anyone... so 50 somethings and above, Get Er Done!"

Thank you to Angel, John, Kathy and especially Dr. Wendorf for not only being professional but also understanding an endoscopy can be stressful for the patient. Thank you all for a wonderful experience!"
"I've had chronic GI issues for the last several years and was originally a patient of Dr. Masters, who helped me start using an Enterra stimulator and get back to living a mostly regular life. Wendorf has taken over for Masters after retirement, and I genuinely could not be more pleased. He is interested in the problems I have, engaged with useful solutions and is easy to speak with about complex health issues.

He gives you such a great peace of mind just by knowing that he is there and he will do the best he can to make sure all your questions are answered. I highly recommend Dr. Wendorf!!"
"I highly recommend Dr. Wendorf. He is the first Gastroenterologist, in the last 3 years, who specializes in gastroparesis. I have been misdiagnosed with celiac disease by one previous doctor. I was told my problem was 'stress!' by the second doctor. So I have suffered with incompetent doctors. Dr. W. was very personable, took all the time I needed to discuss my stomach issues and is very knowledgeable. I couldn't believe he saw me on time! All these other doctors, not just in the gastro field, think nothing of making me wait 1/2 to one full hour-not acceptable. His staff member Wendy is also a pleasure to work with."
"I'm so impressed with the quality of care I received from the staff and Dr. Wendorf. I had a fear of having a colonoscopy because I lost my dear grandmother from one years ago. They explained everything in detail until I felt comfortable. was shockingly surprised when I woke up in recovery to my husbands smiling face. They followed my instruction to have my husband be the first person I see when I woke up. Thank you so much to the staff and Dr. Wendorf for taking care of your patients and our peace of mind!"
"Before my procedure, I was extremely nervous of what to expect but Dr. Wendorf and his staff were wonderful. All my questions were answered and I was assured that I was in good hands. My procedure went so smooth that the day after, I started telling all my friends my age that they need to get it done. I will definitely refer anyone to his office. Thank you."
"I went in for my first colonoscopy. Without any hesitation, I can say that the hardest part was drinking the prep and not the procedure itself. Once I arrived, it was only a few minutes before I was brought to the back. The lady who walked me through the 1st step of getting changed and into the bed was great, and helped me relax. Not long after that, I was brought into the room for my procedure. I talked to both the anesthesiologist and the doctor and both explained what was going to happen. I thought it would be scary but it was fine. The next thing I know, I'm waking up after it was done. The doctor comes back and explains everything. Fortunately, I received a print out of my results since I was a little out of it from the anesthesia. The staff contacted my driver and took care of everything. Nobody really wants to have a colonoscopy, but this experience was the best I could hope for. Everyone was professional, efficient at their jobs, and very nice. Thanks to all who helped me."

"Friendly staff. Dr. Wendorf was very personable and easy to talk to."
"I recently saw Dr. Wendorf at GastroConSA for my severe Gastroparesis. I absolutely LOVED seeing him, it was like a breath of fresh air! He actually APPRECIATED my long winded history and thanked me for sharing it, as opposed to other doctors who frequently brushed me off. I felt seen and heard for the first time in a while! He had some ideas on possible treatment ideas and ordered labs (which I got done same day in house!). For the first time in YEARS, I have more hope for a better quality of life. If you feel like you’ve been to a million doctors and none of them are working for or with you, I suggest you try one more; Dr. Wendorf! PS. The office is ADA accessible 💕"
