If you only read one review; this one might save you from a life threatening experience. I had the Orbera balloon placed and after 7 long days and nights of vomiting and an inability to eat or drink anything, had emergency surgery to have the device removed. It had inflated to fill and block my entire stomach. Dr Heydari and staff did not listen to my pre surgical emergency concerns. He saw me one day prior to my removal and stated to me that I never mentioned any distress. Please consider.....

It is incredible being given the wealth of knowledge prior to surgery was priceless. I knew what to expect, so in turn there were no concerns or anxious moments because everything had been explained so throughly you knew what to expect. He is also has sn incredible bedside manner. You never feel as if your questions are taking to much of his time. The follow up was impressive. The day if surgery he checked on me three times. His staff is amazing.

The most intelligent, caring, kind, medically knowledgeable Surgeon out their in his field. When the surgery is done you aren't forgotten he follows up with you for as long as you need him too. For that I am grateful. He cares and respects you as a whole person. He encourages you. I am 12 years out on my surgery & have gained zero back. He was a gift. I would not be here today if it weren't for his surgery.

Dr. Heydari was calm and professional from the moment I met him. He diagnosed and recommended my procedure well, explained things in a calm and professional manner despite my wife and my own anxieties and fears. The surgery went perfectly and I was back on my feet in a matter of days then back to work in a few days more. I highly respect and appreciate the skill and professionalism of Dr. Heydari.

Dr. Heydari was awesome! Unfortunately, I can not say the same for his office members. I was told by them I was approved by my insurance for surgery and, therefore, proceeded to make all necessary appointments and arrangements. However, after weeks of preparation, I received a letter from my insurance company stating I was denied. Once the office appealed, they wasted another week because they neglected to send in the appropriate paper work. The people in the office were extremely incompetent!

My esophageal cancer surgery with Heydari at Centegra - McHenry was a disaster and ended up at Loyola for rectifying surgery, Was 7 months in hospital bed. Would not recommend for this type of surgery.
