    Almost ten years ago, after seeing several other prominent gastroenterologists in Palo Alto who thought I was a little crazy, Dr. Marcus listened to my story, looked at my test results and knew immediately what the problem might be. Two months later I received surgery and have been well ever since. I have had three endoscopies and three colonoscopies and would never go anywhere else. Dr Marcus sees one patient at a time and gives each the time he and they need regardless of the clock.

    Dr Marcus although a sweet kind man can be hurtful with words sometimes. He doesn't really understand that people with diseases like Crohns and UC aren't always rich or full of reasources so he demand unrealistic goals from you. From going to hospitals on a hope they will do surgery, and gets upset when a surgery can't be confirmed so you have to put work first. That would me one issue as he is working he is paid we aren't working we are trying to survive. Also appointments require a long wait.

    Wonderful experience! Appointment was made without issue - they followed up to confirm the date. Efficient front office. They ran on time and processed me quickly. I was called in before I could even finish my forms. Incredible consultation with Dr. Marcus' PA prior to procedure - she was very thorough and didn't miss a thing. I'm impressed and glad I've switched GI physicians. Highly recommend. Will update after my procedure.

    I was required by the receptionist to make an appointment to see Dr. Marcus for the first time prior to colonoscopy. When I arrived at the office, I had a consultation with his staff instead (without prior knowledge), and was charged as if I had seen the physician. In my personal opinion, the consultation is unnecessary and a waste of money. I then had the colonoscopy done by a renowned gastroenterologist without requiring a consultation prior to the procedure.
