"I've never had GI issues, but recently had a positive test, requiring me to have a colonoscopy for the first time. This was my first visit with Dr.Wadas. He was thorough in going over my medical history and the various medications I'm on and I felt very comfortable with him. I was able to schedule the procedure within a week. Tracy was awesome and so helpful! She thoroughly went over the prep work and what I can expect. She gave me her direct number and told me to call with any questions no matter how small. So far, my initial impression is a positive one!"

"Dr Wadas performed colonoscopy and endoscopy on both my husband and I. He was professional and knowledgeable. He took the time to throughly explain the procedure and prep work involved. When the results came back, he met with us to review findings. (All results were fine) He explained results and made recommendations to ensure optimal health.

"Dr. Darrell Waddas is one of the best gastroenterologist in Arizona. Dr. Waddas is very thero and takes his time explain every detail and questions that you may have. I would definitely recommend him to anyone of my family members or colleagues."

"I've been seeing Dr. Wadas for nearly two decades and have had nothing but the best experience with his care and service. I like to say he knows me inside and out, which is exactly what you should be looking for with a gastroenterologist. He and his team make it comfortable to be incredibly uncomfortable. And they have clean bathrooms too (trust me, this will matter). I'd say he knows his s###, but that would be uncouth, even though it's totally true."

"Dr Wadas was recommended by a friend who works at Banner. I'm grateful to her for leading me to this office! Unsatisfied with poor service by another gastro and her office, Dr. W's office/staff are exceptional. Quick, responsive, happy, great with instructions. Someone on this site mentioned Dr W prep was so much better and it was! He also made sure I was fine after and explained areas of concern. Dr. W took time to listen and ask questions. Not the usual 19 min and run."

"Dr. Wadas has been my GI doctor for almost 17 years. Dr. Wadas took the time to call the radiologist that read my CT scan, while I waited. He is thorough in explaining everything in detail, and also takes the time to review my other health issues. His staff is also professional and welcoming. I highly recommend Dr. Wadas!"

"I was referred by a friend of mine that said Dr. Wadas was the best. I wanted a second opinion on all the work that a different GI Doctor had done. I am rating him with a 5 star because of how comfortable he made me feel. He asked all the necessary questions and even asked me if there was any other questions that I think he might have not asked. I am definitely coming back to him in hopes that he finds the root of my problem. I highly recommend him. ❤️"
