"Dr Niraj Singh was outstanding ! Dr. Singh took all my worries away and left me peaceful About my colon surgery. He took all the stress and worry away out of planning for the procedure. He’s the most gracious empathetic surgeon I have ever met . I recommend him to everyone who asks. Ron Nachtwey"

"After being treated for Colitis by several GI doctors over a 2 year period, I was finally referred to Dr. Singh to address rectal bleeding and an uncomfortable bulge at my rectum. He treated me by banding 2 bleeding hemorrhoids and he diagnosed the bulge as prolapsed hemorrhoids. Not one single GI doctor could interpret my condition correctly. I had spent years thinking my insides were falling out, but Dr. Singh actually listened to my explanation and correctly made me well again!! Wish I had visited Dr. Singh years earlier as I feel I’ve wasted a good chunk of my life. Thank you again Dr. Singh"

"My husband was diagnosed with rectal cancer approximately two weeks before Christmas 2015. It was considered stage 2/3. He would need radiation, chemotherapy and surgery. He would also need a colostomy, possibly for the rest of his life. Being a 52 year old man, the thought of a colostomy for him was as bad as the diagnosis of cancer. Dr. Singh was recommended to us by his primary care physician. When we met Dr. Singh, my husband and I were both terrified. He was so calm, matter of fact and confident that my husband felt confident being in his care. Each time we met with Dr. Singh, we left feeling more confident and hopeful. My husband had his surgery after radiation and chemo and it was very successful. There was no sign of cancer and there was a sliver of hope that the colonoscopy could be reversed. My husband underwent more chemo and after regaining his strength and some additional procedures he was able to have a reversal of the colostomy. My husband has his life back and we both very ...
much feel that we owe Dr. Singh a great deal of credit for this second chance. Yesterday, my husband and I celebrated our 30 year wedding anniversary and he got a clean bill of health from Dr. Singh. I cannot speak highly enough of him and all of his staff. "

"Generally good, no frills service. Poor billing and communication from their parent company Arizona Advanced Surgery. If you choose to come here, be sure and get a quote for services in advance or you may be in for a surprise. Went to Dr. Singh for an in office procedure that I was in and out of their office in about 30 minutes. The problem was resolved. The service received was quick, to the point and direct which I appreciate. However, I was not thrilled to receive a bill from Arizona Advanced Surgery, their parent company, for a new patient visit charge that was just over 50% of the actual cost of the procedure. I understand that new patient fees are assessed but if so, shouldn't I have received more comprehensive service from them? Shouldn't someone have maybe even taken my blood pressure or vital statistics? I was told by Arizona Advanced Surgery that this $331 new patient visit was actually at the low end which seems shocking to me! By my math, that means they are charging at ...
a rate of $1,200 an hour? I was also encouraged to get a colonoscopy which I don't have a problem with. But I am now leery of how much this is going to be and what additional charges. I asked the office for a detailed price breakdown and have yet to receive it. The billing department at Arizona Advanced Surgery did not seem interested in keeping me as patient and basically said the charge is what it is. Ok then, guess I'll be shopping around to find another surgery center. "

"When you are having problems with your colon, you need an experienced and well educated doctor. Dr. Singh and his staff will put you at ease. Dr. Singh will take the time to explain what’s going on with your colon, and what steps are needed to resolve the issue you are having. If you are experiencing issues with your colon and want things done right the first time, I highly recommend making an appointment with Dr. Singh."

"I wish I had gone to Dr Singh 10 yrs ago. 100% better"
  • October 1, 2022
"Dr. Singh is a very compassionate and caring doctor. He is very busy but makes time to understand patient’s concerns and needs. His office team and software need more attention. For example, I had supplied all the check-in information online before the appointment but they had no record of it when I arrived so I had to fill out the paperwork again in the office. The wait time was also longer than normal this last appointment. "
