"A TOP NOTCH DR After 20 years and different Doctors, I finally got a Dr that found what was causing all my esophageal/stomach problems. I had wondered if it was my hiatal hernia. An upper GI was done the day of my appointment with Dr Alan Posner, located in the Buffalo Hospital. After he introduced himself, he said he had bad news for me (surgery) and good for him (he’ll be doing it). I can usually go on my first impressions and certainly was right on this one. He was so thorough, drew sketches (said he wasn’t an artist which was true) but I got the “picture” of what had been going on in my body. We discussed problems I was having which were getting much worse in the past year. He explained things that were probably happening, which were. He showed my husband and I the scans, one of which was done in January this year locally which showed the stomach twisted and up into my chest area. He was surprised that none of the Doctors I had seen saw it. All the previous tests I had ...
done locally showed within normal range, which they were not. He spent so much time with me that day explaining what the problem was and how it started with the reflux/gerd and progressed to the present. He discussed the laparoscopic procedure he could do which would correct the problem. I have had and still do have some great Dr’s locally and in the Orchard Park area but I think Dr Posner is at the top of the list for detail and bedside manner. He made me feel so at ease. He not only explained the para esophgeal repair and showing how the procedure would be done. He was honest about how I would feel afterwards and why. At 77 I wasn’t too excited about having another surgery as I have cardiomyopathy. My stomach wasn’t going to get any better and he said one good thing was that the blood flow was still good. So we went through with the surgery and he wasn’t exaggerating how I was going to feel afterwards. In a couple of days I started feeling better. I was on pureed, strained food for about 10+ days and now on soft foods and will be gradually eating normal. Dr Posner spent almost as much time on the pre op follow up as the first visit. I’ve never been to a Dr that made you feel like you were his only patient of the day. His demeanor is so laid back and I couldn’t get over how much he explained everything in detail. He was the BEST. We are always quick to complain about something or someone negatively but do not take time to give credit to someone who does something above and beyond the norm, not full of himself for it, but glad he can do it to make someone feel better. He is definitely one of the best and am so glad my local Dr did refer me to him. A week and half later and I’m feeling great-no more issues when I eat. Thank you Dr Posner, wish there were more like you. "

"Dr. Posner saved my life. He’s extremely thorough, and if you follow all his instructions by the “book”, you WILL be successful throughout your weight loss journey. Because of Dr. Posner, I have actually been able to live my life as I always wanted. I don’t think my surgery would have been so successful, without any complications had I went with another surgeon. I started off around 350+ lbs and have gone and remained down to 180 lbs within two years. "
