If you can get passed the pit bulls at the front desk, you have a chance at being taken care of by a good doctor. I was treated so badly on the phone that I had hang up. I will never step in that office again for the disrespect I was shown by his staff.

I received a bum's rush from the minute I stepped in the office even though it was my INITIAL visit. I did NOT receive a thorough exam. Dr. Coronel did not ask when my symptoms started, or my pain level. He said I had IBS and told me to take IB Gard and Miralax. He did not talk of a diet. I was not given time to ask questions. He helped me off the exam table and said I'll walk you out. I, "so help me God", did not even have time to button my waistband! Dr. Coronel was rushed and uncareing!!!

He is the best.I had a pain in my stomach for more than 10yrs and couldn’t figure out the cause. Dr. Mark in my first visit ordered hida scam and was able to pinpoint the problem that was related to my gallbladder. He is very easy to talk and he no BS. Will get to the issue right away. He was also my doctor for my first experience with colonoscopy. I’ve to say it was ez pezy, thanks to him and staff

I came to him From PBMC ER. Office scheduled me a apt the same day and he was very helpful ordered all necessary testing. I ended up switching to him from my previous Gastro doctor because of how comfortable he made me feel and his knowledge.

I've been seeing Dr. Coronel for chronic GERD for about a year now after being referred from a colleague. Great Doctor and he went out of his way to get a prior auth with my insurance company so I would not have to pay out of pocket for my medication.

I've been to many GI doctors for my IBS over the years and I have never felt comfortable with their work up and treatments, this is the first time in years I feel I am being managed properly. Great staff, beautiful office and super friendly down to earth doc.
