Everything went went smoothly and professionally. The procedures aren't exactly a trip to Disneyland, but the staff is very proficient at making them be as uninvasive as possible. So I'm glad I did it, I'm pleased with the staff, and I'm glad it's over.

Dr. Treyzon was absolutely incredible. I met with him yesterday and he made me feel so comfortable and so heard. You paid attention to me and everything that I was saying, from start to finish, there were no distractions. He answered all my questions and described everything in detail. I have seen many Gastroenterologist and none of them were as caring or spent that much time with me. They usually just ask me basic questions and I leave very frustrated with them. I felt so hopeful and so seen. Im excited for him to be on my team for my complex case. His office can be a bit warm in temperature, dress accordingly. Highly recommend!!!!!!
