					I was diagnosed with IBD almost thirty years ago and have always been fortunate to find excellent, caring gastroenterologists, wherever I have lived. Jeffrey Unger ranks high among them and has been my trusted doctor for over ten years. He has a great sense of humor, a wonderful bedside manner, no "god complex" and treats me with kindness and consideration. I appreciate that he explains why he thinks a procedure or medication is indicated but always graciously allows me to weigh in on the final decision. That's very important because I know my own body and I am well-informed about my condition. He has performed several of my colonoscopies and I have no complaints about the care he provided or about the surgical facility where it is done. I have referred several people to his practice, among them, some of my dearest family members and will continue to do so. As for the staff, I have always been treated well and as busy as they are, they always make me feel like I'm a valued patient.

					First off, I just want to say the office staff was nothing short of AMAZING. Initially, I had an issue on my behalf with scheduling and they handled the situation efficiently and rescheduled me with no problem. VERY PROFESSIONAL. The office staff really made me feel Iike like I was apart of the Gastromed Healthcare Family. Dr. Wiesen is great as well, very informative, and he made me feel comfortable. I explained my symptoms and he immediately knew what was going on and got to the bottom of my situation. He scheduled the appropriate test and with his insight, almost immediately I began to feel better. I highly recommend Dr. Weiser and the Gastromed Healthcare Family.

					I meant to write this review last year and I guess I never did but I cannot say enough good things about Dr. Weisen and Mel. Dr Weisen was able to figure out what was going on with my stomach and I have been doing so much better since then and Mel is the best at handling all the information and everything I was giving her and relaying it to the doctor and getting my prescriptions where they needed to be and was always on time
