Arrogant and doesn't listen. Exam room wasn't very clean, waste can overflowing. Was asked if I wanted a heated blanket but one was never brought when I said I did, even after reminding the attendant. (had chills and was shivering). Why ask if you aren't going to follow through? Totally dissatisfied with entire visit. Will not go back.

Greydanus was my GI for severe cd for 2 yrs.He stopped my biologic therapy and did solo thioprine therapy which gave me a very serious infection and lengthy hospital stay.Then he dodged answering to the hospital physicians caring for me inpt.Within a yr of firing him,I had got on biologics and had a bowel resection.His legal team seemed most interested in me after this event which led me to fire him. He was abusive, rude, emotionally abusive to me, and his staff,I wish him only the care he gave.

Dr Greydannus was very short with my wife after performing an endoscopy on her, letting her know that she should stay off her prescription of Reglan until her Gastric Emptying Test the following week. My wife got too sick from not taking her medication, and her PCP told her to take it until 24 hours before the exam. Now were waiting over a week for her test results from her emptying study after being told it would take 3-5 days, nurses keep telling me their wating for Dr G to review test results

I have been going to Dr Greydanus for 20+ years - he is very good at explaining any/all diagnosis & treatments he's prescribed. He's a very good listener & is always up to date on my condition. I would recommend him to anyone needing gastro attention. I appreciate the great care he has taken treating me with Crohn's for 20 years.

Both experiences with this doctor have been very negative. He doesnt listen and practically throws sample prescriptions at you before knowing whats going on. He also comes off as rude and arrogant.
