"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!"

"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."

"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."
