Dr. Treyzon has incredible expertise, and is an exceptionally thorough physician. His approach is to treat the whole patient - not just the symptoms. He is a physician who persistently thinks through all the possibilities, does all the necessary tests, and listens to his patients. He is VERY responsive, and you are never left waiting for results, or a call. His staff is on top of it, and he always makes himself available - despite his busy practice. He is very accomplished as a physician - and still treats his patients like family. This is so rare these days. Our entire family sees him, and we are lucky to have him as a doctor.

It is my pleasure to share my experience that I had with Dr.Treyzon. This being my very first visit and feeling ill for quite a while, I was very concerned about my symptoms and meeting a new doctor. I made my first phone call to the office and spoke to Amie, I learned that she is Dr. Trezon's assistant. She was gracious and very professional, as she Informed me about my visit. I made my appointment. Soon I would see the doctor, I was then greeted in the reception area, with such warmth by Dr. Treyzons nurse Anna, as she compassionately reviewed my symptoms with me and prepared me to see the doctor. When Dr. Treyzon entered the room, it took only moments, to know when a doctor CARES. As he began putting the "puzzle of my symptoms" together, I felt hopeful… I felt at ease… and I also felt, that not only my problems would be treated but this is a beginning of a new journey, a healthy journey with a doctor with great knowledge and deep compassion. Thank you Dr.Treyzon. With gratitude, Linda

Dr. Treyzon is exactly what you are looking for in a doctor. At our initial appointment, he never looked away from my husband and I one time, he listened to everything we had to say even if it wasn't applicable and asked questions to try to understand the full picture. We knew right then that he would be the right provider for our uncertain ailment. Since that appointment, he wrote and called us countless times to ensure that we were takin the proper medications and understanding the process. In addition, his staff is extremely helpful, friendly and knowledgeable and was even able to schedule our procedure on a Saturday as it is more convenient for us. We have and will continue to recommend Dr. Treyzon to anyone in need of GI services. Thank you Dr. Treyzon!

I have known Dr. Treyzon for 8 years. He took care of my daughter when she was hospitalized and had GI complications after spinal surgery. He was really helpful and warm in our moment of need. We were so impressed with him then, that the whole family started seeing him. My husband, daughter, and I have all had procedures without any problems. it was a nice experience, as good as that can be. Dr. Treyzon is one of a kind in that he listens to my own perspective and my preferences for how to address my concerns. He is willing and enthusiastic to collaborate with other providers like dietitians, accupuncturists, our pain manager, and our primary care physicians. He is focused on the big picture of our global health, not just the GI problem. he readily admits when there are better tests available to diagnose or treat my problems than those available at Cedars-Sinai. There is a sense that he will treat us like he would treat himself or a family member. He explains things really well. Visits are not rushed. I also email with him often. He responds at night and weekends.

Dr.Treyzon is an amazing doctor! I felt so comfortable talking to him about uncomfortable issues as GI issues can be! He is highly knowledgeable, very professional and he took the time not only to explain my condition, but also to answer any questions I had, even after I left his office! I highly recommend Dr. Treyzon!!!

The first time I met Dr. Treyzon, I was blown away. Clearly part of a very busy practice, I thought I’d get maybe 5 minutes of his time to quickly try and explain to him what was going on with me and determine a strategy on how to move forward. I couldn’t have been more wrong. He sat across from me asking questions and gathering information with a laser-focus on my health and me. I never felt rushed and was astounded by the amount of time he spent with me. He took time to explain everything and the genuine concern I felt coming from him put me at ease. He had just met me and yet I felt like getting me to feel better was his top priority. Since that first visit, he came up with a diagnosis and treatment plan that has served me well for the most part. The part that hasn’t is self-inflicted because let’s be honest….who wants to do the FODMAP diet for the rest of their life?!? Half my favorite foods are on the elimination list! My company also changed insurance 3 times since I started seeing him and his assistant Amie has been so helpful in determining my coverage and letting me know what to expect. There’s a real desire on their part to get me the best medicine for the most affordable price. In fact, when one of my insurance companies denied the very expensive antibiotic I needed, they put me in touch with another pharmacy that helped me to obtain the medication needed through an assistance program…and they delivered it to my home. Amazing! It hasn’t been a smooth road in the year and a half I’ve been seeing Dr. Treyzon as there have been additional developments with my health. His unwavering support and concern have been proven over and over by his availability to me at all hours, and always with such a calming influence. He answers his own emails and always much more quickly than I would expect anyone with a practice the size of his to be able to do. I honestly don’t know how he does it, but I’m grateful he does. This must be what it feels like to have a doctor in the family…and at the end of the day, isn’t that type of care we all hope to get?!? Well, look no further because that’s what you get with Dr. Treyzon and his staff!
