"Dr. Cahill is a good gastroenterologist who is very knowledgeable. She she listens to you before making any decisions and partners with you on those decisions. I’m confident in her abilities and guidance whenever I have an issue."

"Dr. Cahill is AMAZING. She always listens to everything you have to say and encourages you to do research on medication and is very transparent with all the treatment options. She never makes me feel pushed into anything and that leaves a lot of the treatment decisions with me and educates well!"

"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!"

"It was a pleasure to meet Dr. Cahill. She was very pleasant and professional. She took the time to answer all of my questions and concerns about my upcoming procedure of my endoscopy copy and colonoscopy and gave me options as to how I would be sedated to ensure my test went smoothly. 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 would recommend Dr Cahill to anyone looking for a gastroenterology doctor who really cares."

"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."

"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."
