Getting test results often required repeated follow-ups, and appointment wait times were frequently excessive. My most recent visit was unacceptable. I came in for a follow-up after a serious hospital stay and was turned away because the office claimed they hadn't received a fax, despite it being sent the prior week. No real effort was made to locate it, and I was even refused when I offered to email the records myself. Dr. Dyer never spoke to me directly and instead made dismissive, disrespectful comments to staff within earshot. Given the length of time I was a patient and the circumstances, this was deeply unprofessional. I will not be returning and do not recommend this practice.

I've been calling her office for months, leaving messages. No return phone calls whatsoever. Then she refused to fill my medication again, even though in her own very words, this was the only medication that was left on the market, with the exception of Famotidine. She only works two days out the week Monday and Wednesday and I called leaving several message, begging and pleading for someone to call me back. Never received a return phone call for months. A horrific horrible experience. She did absolutely nothing to help me. If I could give her zero stars, I would. She should be ashamed.

My physician referred me to a doctor who had an extremely long wait list, (December) to me, it was way too long to live with a 'what if I have..?' So the scheduler suggested Dr Kulik. I live in the suburbs and the Northwestern hospital downtown location was a last resort. I arrived an hour early and Dr Kulik's nurse brought me back just moments after checking in. That was a nice surprise. Dr Kulik showed me the results of my blood tests, asked a lot of questions and was simply the best doctor to be on the other side of a scared, nervous and worried patient. She ordered a few more tests to include an MRI. Dr Kulik and I kept in touch via my chart as I'm a tech geek so I want to be on top of things..what were the results, What does this mean, blah blah blah. And she was always responsive as was my primary physician. I can't say enough wonderful things about Dr Kulik.

She's an example of what a health provider should be.

I'm so glad I got referred to him, as I think he's the bee's knees. No one likes talking to the doctor about the grossness that's going on in your life, but hey, that's all a part of his job. He must like talking about it too since that was his chosen specialty! Long of the short of it, I felt super comfortable talking to him, and it helps he's got a great personality too. He takes the time to listen to all your questions as well as give you feed back as to what you can do to improve the situation. Dr. Williams also does his "homework" and reads up on your files and remembers conversations that you've had in the past. In this day and age, it's hard to find a doctor like him.

It never happened to me in last many decades. I refused to do so because as per my knowledge and law a patient can pay his/her bill or dues through cash, check or credit/debit card. It is an unlawful practice and made up policy of MDHN for its own financial business malpractice in my opinion. Besides, As best of my knowledge I have no dues but in case If I had one which I was not aware of it, I must have been provided the bill at the desk on the day of appointment or I should have been told about it at the time when I made appointment or they should have sent me a notice ahead of time but they failed to do so and my rights to see the doctor was violated. The counter girl was very rude and uncaring. Not only she wasted my time and played with my serious medical conditions (I am 80 years old, I have brain tumor, spinal, nervous system and serious stomach problems and I have gone many procedures) but also my right were violated.

Dr. Cohen really spends a lot of time getting to know your symptoms and thoroughly investigates your health history for an accurate diagnosis.

I have seen other GI doctors who told me things that were completely false, and or informed me to eat enough fiber which I already count and do as a vegetarian.

I could not have asked for a better experience. Dr. Lotsu and the entire team are all very…read moreprofessional, very nice and very knowledgeable. I had put off this procedure for 5 years because of all the horror stories I had heard from others. The team was very understanding, proactive and the instructions were very clear. I appreciated all the text reminders too - that was extremely helpful!! I am so happy I followed Dr. Lotsu's instructions rather than the ones that were on the prep box or the various "tips" I read when googling this procedure. Dr. Lotsu and his team have made what is usually described as one of the most unpleasant screening procedures as professional and as "good" as it could possibly be. The procedure itself is definitely not pleasant - but I'm certain that developing and/or fighting cancer would be 1000x worse.... The most discomfort I felt was from having to go a day without eating and I was so freakin' hungry. The prep wasn't even bad - the taste was fine. The exorcism of the demons wasn't that bad either - I was expecting an intestinal terrorist attack, but it really wasn't horrible and it was over in an hour. Dr. Lotsu personally called me with the results later in the day and explained everything to me. He is very professional but also very personable. If I have anything un-positive to say or any suggestions for improvement, it would be that I expected to be 5 pounds lighter this morning, and the weight loss was only 1.4.... and that pillow was super comfortable - I could have slept for another hour or two. Maybe next time - ?

I first contacted Dr Osipova in late 2017 to consult about recurring hernia issues. She was…read morefantastic during my consult, answering all of my questions, drawing pictures, etc. Dr Osipova suggested I also meet with her partner for a second opinion, Dr. Adajar, who has a different perspective on how to treat hernias. So I made an appointment and did as she advised. Drs Osipova and Adajar were just as fantastic during that consult. I determined I was not going to go forward with surgery right now, but would work on some lifestyle issues to see if that would help. I had blood drawn and Dr Adajar let me know numbers and his recommendations based on my numbers. And then it went downhill. I talked with Dr. Adajar's assistant Michelle, and felt like I was being sold a used car. She wouldn't let me talk, and was just throwing out price tags for consultations that needed to take place, weight loss medicine and vitamins and hormones I needed to buy, etc. When I would try to talk, she wouldn't hear me and I finally just asked her to have Dr. Adajar call me so I could understand what this Xsculpt work was that he does, and talk through what would be the best course of action for me to take next. That request to talk to him was made over a month ago, and I haven't heard from him. I even texted him on his cell, since he used that form of communication with me after my blood test results were in. I got no response. The experience started out great, but then turned into something I didn't understand. And I am left with a bill to pay for the bloodwork and no course of action to take that you usually work out with a medical professional. I wanted to let others know about my experience here so they could take it into account if they decided to visit this office.
