"I visited several facilities before choosing Desert Endoscopy Center. This one stood far above the others. Every single person there was friendly and kind. The facilty itself is very clean and the chairs in the waiting room were noticeably comfortable. Dr Grade was very competant and reassuring taking his time before and after the procedure to speak with me without rushing. I appreciated the kindness of Dr Grade and all the nurses and staff. Highly recommend Dr Grade and Desert Endoscopy Center."

"I came in to see Dr. Grade during a severe flare-up of my IBS, but was scared it could be something worse. He listened to all my concerns compassionately, took my symptoms seriously, and made me feel like a valued patient. I wasn't rushed or dismissed as many doctors can and do. I really felt cared for and knowing my financial hardships, he started slow with treatment and tests based on my affordability, eased my worries, and assured me I was in good hands, and set up a follow-up appointment to see if my symptoms had improved. I came to him because he is also my Mom's GI specialist and has taken good care of her, and it was great to know that he consistently offers the same care, compassion, and communication. I also feel his office staff upholds the same values and takes care of the patients' needs and concerns consistently from start to finish."

"I have been seeing Dr. Grade for over 5 years. I credit him with saving my life. I feel the review regarding calling for “2nd Opinion” as unfair and has nothing to do with Dr. Grade himself. He is part of a group, Arizona Digestive. Whomever answered the phone does not even work in the office where Grade resides. Perhaps they needed a referral? With that said, I gladly drive all the way to Queen Creek to see Grade. This review is about DR. GRADE. When he first started treating me, I had rapidly lost 40 lbs in one year, 50 total, with no effort. I was terrified. Dr. Grade approaches his patients as a “whole entity”, not just with his specialty in mind. He was Uber responsible; sending me to an oncologist, getting me into Mayo for specialized tests, ordering all the right tests, all the while LISTENING and believing me that I felt I had an autoimmune disease, not just Gastroparesis. Because of him, his willingness to support non-FDA approaches (Botox treatments on my stomach, writing a prescription for Motilium which I get overseas and HELPS my stomach to digest, getting me neuro, colonic, pelvic floor function tests, making sure I have a cardiologist, etc) he has literally “saved” me. I have my diagnoses, treatments, and can live with some quality of life. He CARES. And because of him,we have connected many dots as to what is going on with my body as a whole, and I ended up with Dysautonomia as well (which I would have never known had he not gotten me into Mayo for tests)—huge connection with Dysautonomia & gastro paralysis!! most doctors wouldn’t listen or work that hard to get answers. I’ve been able to avoid a feeding tube, and gain weight. Dr. Grade is, without hesitation the best doctor I have ever encountered. And that is saying a lot coming from someone who worked in the medical field with MANY doctors (me). He treats the patient, not just the symptom. He has been voted one of the best gastroenterologists in the COUNTRY. And, he deserves it. I’m LUCKY."
