Dr. Andreas Kaiser, MD

I seldom leave reviews but I love Dr. Kaiser so much. I have a complicated case of colon cancer with an advanced tumor. He performed a very successful surgery and I am forever grateful. He has a dry sense of humor that I really relate to and he helps me feel more at ease despite my (extreme, at times) anxiety. I like him so much more than my previous surgeon. If you need this type of surgery, go see him!

Doctor Kaiser is THE DOCTOR, who will safe Your life !I was diagnosed with stage 3 rectal cancer in 2023.We've met with Doctor Kaiser & immediately loved his very clear plan for me.He is very calm, polite, informative, compassionate: he made me drop my fears, explained all details of upcoming surgeries.I had 1st very successful surgery in December,2023. Stayed in hospital 5 days and my Doctor with his team visited every day, making sure I am OK. Second smaller procedure was done in outpatient facility this week, all great ! My final,successful surgery was 15th of August,so excited for my new healthy long life in future. Blessed to know Doctor Andreas Kaiser & I recommend him from the bottom of my heart !Very amazing fact: being from Switzerland, Doctor Kaiser speaks Italian as well (among other languages) & my Italian husband was very comfortable with asking questions in his language without being too nervous of not understanding some facts in English :) Grazie mille,caro Dottore !

Doctor Kaiser listens and will explain the best option. He has been my doctor since 2018. I followed him from the previous hospital to City of Hope.

I certainly would, I had surgery performed by Kaiser’s team in October 2018 and it changed my life for the better, I had been having feces and blood In my urine. I had a fistula. I had open prostate surgery performed about four years earlier and had had issues with infections, fevers for a number of years and even went to numerous specialists who could not figure out what was wrong.

Dr Kaiser performed a very challenging arthroscopic surgery on my removing my cancerous anus and rectum. He was very available and his office staff is excellent and responsive I am forever grateful to Dr Kaiser as he clearly saved my life. It is two years later and I have had NO recurrance of a very aggressive melanoma of the anus/rectum. I cannot thank Dr. Kaiser enough.

Dr. Kaiser saved my life. After two months in a Kaiser Permanente Hospital, 3 major surgeries, and in ICU on a ventilator in septic shock I was told that I needed to have a bowel resection and possibly a permanent ostomy. I found Dr. Kaiser. I was immediately impressed by his patience, calmness, and expertise. I was terrified to have another surgery. He was firm yet kind. I had the surgery—a triple resection with no ostomy. His surgical skill is beyond compare. His character is beyond reproach.

A true doctor in every sense of the word. Patient, kind hearted, understanding, and has a sense of humor once you get to know him. He is the only surgeon out of five that I interviewed that said he would not place a colostomy bag on me if he didn't have to, and he is a man of his word. More surgeons should model his work ethics.
