Happy, Satisfied Patients

Hear it from the patients themselves!

					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
