I only go once a year and really enjoyed catching up with Dr. Cahill. Everything went fine and I learned a few things also.
1. Organized staff and clinic/OR
2. Helpful and attentive ancillary staff
3. Anesthesia and GI physician both skilled and competent
4. Trusted the entire operation from scheduling through follow-up

I had a very positive experience with Dr. Jennifer Cahill who I found to be thorough, personable, professional and accommodating. She is outstanding at her profession and I am grateful to trust my digestive health to her. I’ve been a patient with NW Gastroenterology (which is now associated with GI Alliance) for 35 years.
Dr. Cahill is highly experienced. She really took the time to understand my case, and made me feel very comfortable during the interview. A+++++++++++++++
Great appointment! Doctor has great bedside manner!
Everyone was very polite and professional. On time, prepared and informative.
Dr. Cahill is friendly and easy to talk to. She does care about her patients. She has no problem answering questions and is not condescending. She's very knowledgeable about the medicine and treatments she prescribes. I'm not thrilled with getting colonoscopies or even being put under, but I trust being in her hands.
Dr Cahill was on top of everything with trying to get to the bottom of an issue I've been dealing with for about a year. I felt relieved knowing that finally I may get some answers. Thank you Dr Cahill
Dr Cahill goes over everything, explaining test results, procedures needed, and when to get them done. We've reviewed my records from my prior physician to gain a better understanding of my condition. I struggle with colonoscopy prep, so she's having me try an option, hopefully more suited to my needs. Dr Cahill manages colon & liver disease, which is exactly what I need in a GI specialist! Thank you, Dr. Cahill. Davida Williams
Dr. Cahill is always there professional and thorough. Dr. Cahill explains herself without getting lost in medical jargon. Dr. Cahill is efficient without rushing and takes the time to answer my questions, when I have questions them. I Highly recommend Dr. Cahill.
Very good experience.. … from scheduling all way through follow up call day after proceduce. Overall very efficient operation with pleasant staff. I felt at ease throughout whole process. Thank you !
Very knowledgeable in her field. She explains my condition and the treatment options available and what she recommends. Very personable and easy to talk to. I feel very comfortable having her as my GI.
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.
