"I came in as a new patient in an emergency situation. I was so fortunate that Dr. Zwas was able to see me that day! She was so generous with her time. She is very knowledgeable, was attentive to my needs, and has a great sense of humor, too. I felt like I had met a new friend who could and wanted to help me! She had followed up each day since my visit both by phone and over the portal. My son came along to the visit and said afterward “you hit the jackpot!”"

"Five star service from start to finish. The people in reception that are making the reservations and the nurses that take your vitals are true professionals. All are polite and knowledgeable. Dr. Zwas is a godsend. Before I met her, and I was in bad shape physically. I honestly believe she has saved my life. As if that’s not enough, Dr. Zwas’s humor and personality matches her stellar skill set. Rick Bria"

"Dr. Zwas is as good as it gets, in every possible way. An AMAZING diagnostician, she anticipated I might have a serious problem so she did a colonoscopy to get to the cause of my problems and prevented a deadly development in my gastro region. I just cannot say enough good things about her...& her manner could not be nicer."

"Dr. Zwas is not only a 5-star doc, she is a 5-star human being. She is a brilliant diagnostician, a caring and empathic healer, and she goes above and beyond for her patients. She has been my GI for 20+ yrs, helping me navigate my IBD through flares and remissions. She understands how idiomatic chronic IBD is, listens to her patients and works collaboratively to find the best path. I cannot say enough about her excellence as a doctor, and her graciousness, generosity and kindness of spirit. You could not be in better hands."
