Together: A Better Way to Fight Cancer

  • Dr. Wingo and her staff are outstanding! I have cervical cancer and have been seeing her for almost 3 years. She is so caring and knowledgeable. I highly recommend her! Her office staff is equally as caring and knowledgeable. They go out of their way to answer questions and offer great patient service.

  • As an RN I have had many people ask for a recommendation and I always recommend Dr. Brooks. He has taken care of my 93 year old mother for 4 years. He actually LISTENS to his patients!

  • Dr. Bhoola was very professional and discussed alternatives with me prior to surgery. the surgery went very well, I had it on a Wed. and home on Thur. with no complications and very little pain. I was back to full strength after only a couple of weeks. I would highly recommend him and his staff.

  • I can't say Enough GREAT things about Snehal Bhoola, M.D. and His staff!!!!. I first had the pleasure of meeting Dr. Bhoola (and staff) back in August 2013, when I had a cancer scare that resulted in non-cancerous, yet resulted in a partial hysterectomy. The moment I stepped in their office, I felt important, I was taken care of to the fullest and then after my surgery, Dr. Bhoola personally called to follow up with me prior to my office visit. I recently had to contact their office again due to health questions, I spoke with Dr. Bhoola's assistant, explained what was happening, she advised she would follow up with the doctor and get back with me. Less than 24 hours Dr. Bhoola again, personally called me to get the full story. I have never experienced such a more caring Doctor and staff, they treat you like family, they are very knowledgeable and you instantly know you are in great hands. I would recommend Arizona Oncology, and Dr. Bhoola 100%, all your questions will be answered, you will be taken care of and you will always feel like you are a person and not just a file. Thank you Arizona Oncology, and Dr. Bhoola for all you do, you truly are One of a Kind!!

  • Dr. Khattab is so knowlegeable and caring. From my first visit, instead of a number and dollar signs, I was a patient that he didn't want to worry about anything. He was so reassuring, he was here to just get me better. Also his MA, Jamie and finance gal, Rose go above and beyond. I always feel that we are welcome. The staff in the chemo lab are always happy and compassionate. All of these things make one terrific office, one that I have already recommended.
