"Dr Cahill is a new GI doctor for my 89 year old mother. She has been fantastic listening to her issues and providing options and advice. I think my mom feels heard for the first time and commented she wishes she could have her for a PCP. I feel she is getting great care and when I need a GI, I know who I will go to now."
"Dr. Cahill is extremely knowledgeable! She listened carefully to my concern and offered medical advice. Dr. Cahill took her time with me and I’m appreciative for her excellent care!"

"Dr. Cahill is very knowledgeable and caring goes beyond and above"
"Excellent care with Dr. Cahill"
"We were pleased to have a cart ride from the UIAA tent to the ticket gate on the East side. If such were available after the game to Lot 31 that would have benefitted me greatly given my sciatica. Also the exit the prior week was terrible from the East stands and having the vendors’ carts blocking the exit lanes on the outside were a major issue. We couldn’t even get out of the stadium hall way!! The Orange Affair was excellent."
"Dr. Cahill exceeded my expectations in every way. From the moment I walked in, she was warm and welcoming, immediately putting me at ease. Her professionalism was evident in how thoroughly she explained everything, making sure I understood all aspects of my care. Despite the sensitive nature of our conversation, she made me feel completely comfortable and safe to share details I might have otherwise found too embarrassing to discuss. Her kindness and genuine concern for my well-being were clear throughout our appointment. I left feeling confident and reassured, and I can’t recommend her highly enough."
"Great doctor! She has helped me tremendously with my IBS. Pays attention and gives understandable answers to any questions."

"Edit 3: It’s been said (below) but it bares repeating, Dr. Cahill is THE BEST! She always has my personal best interests in mind and takes the time to ask questions and truly connect with me. I feel blessed to have her as my doctor. Edit 2: received a call back shortly following my first edit below. Dr Cahill was gracious with her time and explained the results as well as treatment options with me. EDIT: Although Dr. Cahill is wonderful, I need to edit down my review. It’s been 12 days since my procedure and I still have not received results from my biopsy. Dr. Cahill has been so good to me during my treatment with continuing digestive issues. She does not “push” any certain treatment or test but rather takes the time to review all options. Dr. Cahill is also very conscientious of insurance coverage so that there are no major unexpected out of pocket charges. Aside from all of this, Dr. Cahill has made me feel very comfortable in spite of how awkward it can be to discuss digestive issues and undergo a colonoscopy. I’ve never once felt embarrassed with her and that I appreciate so much!"

Dr. Cahill also provided me with different options in terms of treatment and let me know what the possible diagnoses may be. She wasn’t overly quick to recommend invasive procedures, but rather offered a step-by-step plan to ensure I was comfortable to move forward. Being that topics around our digestive system can seem “private” and “embarrassing” it was very comforting to speak with a doctor that did not make me feel awkward or uncomfortable in anyway. I would absolutely recommend Dr. Cahill."

I was with my previous gastroenterology doctor for over 20 years until she moved her office so I'm so happy to have found my new, long term doctor.

"I suffer from Barrett’s esophagus, IBS, and have a history of 18 colonoscopies with benign polyps and the last one a pre cancerous polyp was found. All I’ve ever had by my old GI Dr were Tests ! When I went to see Dr Cahill she said, “ has anyone talked to you about how to treat these disorders ?” I thought to myself , besides ordering prescriptions and laxatives and telling me to watch my diet I never ever had a Dr talk to me about how I might fix these problems! She sat across from me looked into my eyes and spent at least 25 minutes going over my digestive issues, what brought them on, what made them worse, etc., then examined my abdomen and ordered me some new medications and set up an appointment for a study to test the nerves and muscles in my bowel which no one ever thought of checking before. The front desk staff was so compassionate set up another appointment in a month and an appoint for my test. The Rx were at my pharmacy on my way home and ready for me.. What a great experience! Dr Cahill is very compassionate, brilliant, professional, and thorough. She is the Dr I’ve been looking for for years! I’m so glad I finally found an old fashion Dr that is young! That is ethical, , so intelligent, and really cares about her patient. The staff as well. Lizabeth Howell Johnson R.N."
"I had a very positive experience with Dr. Jennifer Cahill who I found to be thorough, personable, professional and accommodating. I’ve been a patient with NW Gastro now called Illinois Gastro for 25 years and find the practice well run. I trust my health with Dr. Cahill and this practice."
"I love that she made me feel comfortable and was not rushing during my visit."
"This was our first visit in the transition from Dr. Sales to Dr. Cahill. Dr. Cahill was very thorough and answered all of our questions. She was very reassuring about a recent ER visit that left us with more questions and concerns than answers. We are confident that this will be a very positive doctor / patient experience going forward."
"Very thorough, approachable, left no stone unturned and easy to answer her questions and ask my own questions. Highly recommend. I have ulcerative colitis and have been with 4 other Gatros in the last 20 years. All were great but feel Jennifer was the most thourough and easiest to talk to."
"Dr. Cahill is knowledgeable, friendly and confident. I am happy to have her as my doctor. Her time working with the VA helping our Vets is something I respect."
"DR CAHILL WAS VERY PROMPT AND MOST ATTENTIVE. SHE THOROUGHLY REVIEWED MY CHART AND MADE APPROPRIATE RECOMMENDATION FOR FUTURE BLOOD WORK. I FELT VERY COMFORTABLE DISCUSSING MY CONDITION AND REASSURED AS TO MY FUTURE CARE."
