"Ms. Lindsay Van Ham ACNP-C saved my husband’s life. He initially saw her for an intestinal issue, and she promptly ordered an abdominal CT scan, which revealed a large abdominal aneurysm. Thanks to her urgent referral to a surgeon, my husband underwent surgery and made a full recovery. She is extremely professional, thoroughly explains what’s happening, and demonstrates excellent judgment and keen assessment skills."

"As you enter, the waiting area gave me a bad impression as it seemed dark and overcrowded. However, dealing with the staff gave me a very different impression. The whole process was well organized. All the staff I met were caring and helpful. (Even to the point of having a case to store my contact lenses and holding a mirror for me as I put them back in!) The anesthesiologist was great and took away the fear. Dr Walker met with me before and after the procedure and clearly explained everything and gave a chance to ask questions. No one looks forward to having a colonoscopy, but the prep directions were simple and not nearly as bad as I feared. The colonoscopy itself seemed to be over in a second."

"They were great. The previous gastro I had visited was an awful experience, did not listen to me, provide any medication for the pain or explain anything that was going on. This doctor at Arizona Digestive Health took the time to explain everything about my IBS and gave me a combination of meds that are finally working and giving me relief."

"Dr Collins is a treasure of a doctor. O know if I tell you just how great he is you’ll want him as your gastrointestinal doctor and he’s already on overload patients. But truly you’ll never find such a careful and kind man as he. And so intelligent reference our bodies diseases and how to advise and treat us. He’s truly a treasure"

"Shauna is an amazing NP. She listened to me, took me seriously and got me testing for what I came in for. She also caught an abnormal lab value and strongly suggested I follow up with my PCP since it was unrelated to my GI issues and now I have a mammogram scheduled thanks to her. Very well rounded, whole person focused care."

"Once I was ALLOWED to see someone, I was very happy with the office. Lindsay VanDam was fantastic. Next stop an endoscopy. Just not pleased with the hoops through which I had to jump since I had been a patient of another recently retired doctor. Very frustrated at having to receive PERMISSION to schedule with a new doctor/office. This was a practice rule rather than an insurance rule."

"The staff was nice and the nurse was outstanding. However, I was upset that we all wasted our time as the anesthesiologist they use is out of network and I wasn't told until I met with the nurse.

I had to leave a meeting early to be here by 11.. just irritating. We'll see how the rest goes... Update to come Ok, well, the rest of my appointment was great! Dr. Umar was very thorough.

"Dr. Vulcano was so nice and took the time to explain everything. When you are scared his kindness really goes a long way. The nursing staff and anesthesiologist were also wonderful and kind on the day of the procedures. His MA was also amazing and made me laugh after the PA scared me out of my mind with a possible dx. That's the negative experience I had. I felt there was no reason to throw out a frightening dx that I hadn't even considered with the statement "do you understand what that means?" which I did. It wasn't that thankfully but the weeks after, while waiting for the testing, were torturous. The rest of the staff from the front desk to the follow up call were fantastic. I will continue to follow up with this office as long as I live in AZ. I can't recommend this place enough. Truly amazing people work here. I'd like to thank them for everything they did to help me through this process."
