    I absolutely wish I could give this man a ZERO. He is arrogant and rude when he speaks to you. He talks over you before you have a chance to even ask a question. If he actually has any human feeling whatsoever toward his patients, it is certainly not apparent in his behavior. I value my life too much to put it into Greenspan's hands.

    The staff are incredibly rude! Very unprofessional.
    My daughter was required to have a scope that was scheduled my his staff. The staff in his office and his nurse practitioner are incredibly sweet and helpful. When we met the doctor after the scope he had no time for us. He called my daughter princess and told her to take a xanax. For two days she was in & the doctor would not return our calls. Found out the real issue. He is arrogant and dismissive towards woman. He prescribed unnecessary meds. I would not recommend him to anyone.

    Spent weeks researching colonoscopy screening service providers and Dr. Aaron Greenspan ended up at the top of my list. This was my first colonoscopy, so I was nervous, but Dr. Greenspan and his staff put me at ease because they all were very friendly, professional, and caring throughout the entire ordeal. The Metro East Gastroenterology facilities looked clean and modern in every room. Being a technologist, I was also impressed with the procedural equipment. I HIGHLY RECOMMEND!

    So I had my colonoscopy 5-25-17 and I have to say I was very nervous for some reason. let me start by saying from the beginning to the end I was treated with nothing but Professionalism. The receptionist was very courteous and friendly. The staff that took care of me during my procedure check-in Cindy, Pre-op Brooke, Nurse Anesthetist Bob ( Thank you so much for the reassurance that everything would be okay!) Nurse Lisa and Recovery nurse Mary who made sure I was feeling okay. Dr. Greenspan 5's

    Highly recommend Dr Greenspan! Great doctor who listens & genuinely wants to help you! I would not recommend his PA, she leaves something to be desired...

    Takes the time to listen to your needs and issues. Has a great sense of humor. Fantastic surgeon. Good bedside manner. Have gone through many other GI doctors and Dr. Greenspan is the best hands down!

    I think he is wonderful, he makes you feel calm about any proceedures you are about to have. He performed a scope & then a colonoscopy. I trust him ??
    He takes little time to actually listen to his patients, and makes hasty decisions without tests. He once insisted that a flare I was having was not in fact a flare, but a bacterial infection and prescribed me very strong antibiotics without doing a stool sample, which made my condition much much worse. He also easily joked about cutting out my intestines, and once casually mentioned that he might have seen cancerous cells during a biopsy but wasn't sure. I was terrified for months.

    I was treated very well by Dr. Greenspan and his wonderful staff, the staff were all upbeat and very personalble. Dr. Greenspan is a very out going and easy to talk to, the prep the day before is not nice but the reward is the great treatment you receive doing and after the actual procedures, if you have this done I would highly recommend Dr Aaron Greenspan and his excellent staff Thank you all. Got a call the day after to make sure everything was going well.

    I had questions for Dr Greenspan regarding my care, so I called his office and left a message with his staff. He personally called to speak with me on a Friday evening to answer my questions. He was very kind and explained everything to me.
